Hey I am preparing to take the TEAS 7 in April, what score do you need to get accepted into a LVN program
I just took the TEAS and passed this morning!! I was crying from stress the night before but your videos helped me tremendously. Now it’s time to party 🎉
Did you study all of her videos and was it enough to pass? I am struggling with what to study. I take mine on the 12th.
@@ashley.petersen I studied all of her science and math videos. Practice tests help a ton. Everything that she covers is mostly mentioned in my exam that I took this morning.
Congratulations on passing your TEAS exam! That's such amazing news! I'm so glad to hear that my videos were able to help you prepare and feel confident going into the test. It's understandable to feel stressed and overwhelmed, but you did it! You worked hard and it paid off. Now it's definitely time to celebrate and have some fun!
@jhailynabelarde7250 where did you take the practice test? Also, how long did you prepare for?
What is the difference between ATI TEAS and TEAS 7??
I passed the TEAS 7 a few days ago. Your videos plus the practice test reviews were super helpful! So glad I went over Mendel's Law of Inheritance and the punnett square☺. I was surprised I didn't have questions comprised of : select all that apply, fill in the blank, or ordered responses. For the science portion, I had questions on properties of solutions, chemical reactions, control group vs dependent/independent, DNA replication, calculating and identifying atomic number/mass, and immune cells. Have a wonderful day!!
Congratulations on passing the TEAS 7 exam! I'm glad to hear that my videos and practice test reviews were helpful for you. It's great that you went over Mendel's Law of Inheritance and the punnett square, as they are important topics in biology. It's interesting that you didn't encounter questions with select all that apply, fill in the blank, or ordered responses. It sounds like you were well-prepared and performed well on those topics. Thank you for sharing your experience, and I wish you continued success in your academic journey!
After reading all these comments on everyone passing after watching your videos I gained so much hope! I'm scheduled to take the teas in 20 days and I've done everything to take advantage of every resource from Mometrix books, to flashcards, practice quizzes, and binge watching UA-cam videos.
That's fantastic to hear you're feeling inspired and hopeful after seeing others' success stories! Utilizing a variety of resources is an excellent approach. Each method offers something a little different, helping to reinforce your knowledge from multiple angles.
With 20 days to go, you're in a great position to solidify what you've learned and fine-tune any areas where you feel less confident. The variety in your study materials will likely keep your prep sessions engaging and dynamic, which is a fantastic way to maintain focus and motivation.
Best of luck - you're going to do great! 🌟📚💪🍀
hey how did you do?
@@anaiyasimpson8085I got a 73% which is a pass for my program (the minimum is 65%.) I start nursing school next week!!
I wish I would have found your videos before I purchased the ridiculously huge MOMETRIX book. You explain everything so well and simplify everything. All I have left is to watch the Chemistry and Math video then I am studying for my TEAS exam in March. Thank you for your videos they have been so helpful to me!
I am so sorry to hear you are having difficulty with the MOMETRIX book. The book can be very large and overwhelming, which is why I created my videos to break down what you need to know for a foundational understanding. You got this bbjaz 😊💜 Keep up the great work.
amazing i’m taking my teas test tomorrow
Same in like 2 weeks these videos help so much!!! Good luck!
Mometrix is good but voluminous ,please do u have a book
I bought the book too. It has a lot of information, but these videos are the best.
Nurse Cheung, I took and passed my TEAS today and am officially a nursing student and I start school at the end of the month. You had a lot to do with that. Your videos on Human Anatomy and Psychology and Life and Physical Science were invaluable. Thank you so, so much!☺
Congratulations on passing your TEAS exam and getting into nursing school! That's a fantastic achievement, and I'm thrilled to hear that my videos on various subjects, including Human Anatomy, Psychology, and Life and Physical Science, were helpful to you. Starting nursing school is an exciting journey, and I wish you all the best as you embark on this new chapter in your educational and professional life.

Remember to take breaks and practice self-care, and don't hesitate to reach out if you need any more support or guidance. You got this, my friend! Best of luck to you on your exam.
I just found your videos and you are a heaven sent ❤ I love how you explain and teach !!! Thank You !!! I’m studying to do my LPN to RN bridge in 2023 ! I completed a Teas exam about 12 yrs ago but I honestly do not know what I scored … it was through my school … is there a way to find out how I did?? I do know I got into my LPN program due to my high science score … I was happy to be in the program and moving forward… so it didn’t matter at the time but now I’d just like to know ..
Keep doing what your doing !!!! ❤️❤️
Hi Sherry Lanham 😊💜 Thank you for taking the time to reach out to me and for your kind words. I am so happy that you have found my videos helpful and that you appreciate my approach to teaching. Unfortunately, I am not sure if the ATI TEAS would still have records past 10 years. I would recommend trying to log into your account and see if the results are still there. You can also try to reach out via email to ATI but I have not always been successful using that route.
Thank you again for your supporting me, and I hope that you continue to find my content helpful as you pursue your LPN to RN nursing education. Best of luck on your next ATI TEAS. Let me know how you do.
Fantastic video. I learned so much. THANK YOU!
You're very welcome! I'm delighted to hear that you found the video fantastic and that it helped you learn a lot. If you ever have more questions or need further information on any topic, don't hesitate to reach out. Keep up the great work in your studies! 😊👍
I’m studying your videos and the smart edition course religiously. I take my test at the end of them month. I struggle with short term memory so I hope to come up with mnemonics to help me remember stuff.
That's fantastic to hear that you're putting in the effort and dedication to study for your upcoming test! It's great that you're using my videos and the Smart Edition course to prepare. Remember, consistency and regular practice are key to retaining the information effectively.
Creating mnemonics is an excellent strategy to enhance your memory and recall important concepts. Mnemonics can be fun, creative, and personalized, making it easier for you to remember complex information. Here are a few tips for coming up with effective mnemonics:
Keep It Simple: Create simple and memorable phrases or acronyms that capture the key points you need to remember.
Visualize: Visualize images or scenes that represent the information you want to recall. Creating mental associations can be powerful for memory retention.
Use Humor or Rhymes: Incorporate humor or rhymes into your mnemonics to make them more enjoyable and easier to remember.
Connect to Personal Experiences: Relate the information to your own experiences or interests. Making it relevant to your life can aid in memory recall.
Practice Regularly: Review and reinforce your mnemonics regularly to ensure they stick in your memory.
Group Information: If you have related information to remember, group it together and create a mnemonic for the entire group.
Share with Others: Teaching your mnemonics to others can reinforce your own understanding and help solidify the information in your mind.
Remember, everyone's learning style is different, so feel free to experiment with various mnemonic techniques to find what works best for you. Consistent practice and dedication will undoubtedly pay off during your exam.
Best of luck on your TEAS test at the end of the month! You've got this! 🌟📚
YOUR SIMPLY THE BEST💯👩🏫🏆, THANKS FOR SHARING!😃
Thank you, Queen Doss! I'm so happy to know that I am meeting your needs and exceeding your expectations. I strive to provide the best possible education possible, and I am glad to have you as part of the Nurse Cheung community. 😊💜
Please let us know if there's anything else we can do for you and don't hesitate to reach out if you need any additional support.
Thank you so much for your content, info is easily understood.
My pleasure dahreal roxy 😊💜 Thank you for the great feedback and review. You got this!
Great video, it really helped me refresh my knowledge of basic biology! I'm also using the Mometrix ATI TEAS 7 book to study and the book has so much more information to read over. The book is really overwhelming as are the practice exams and tests. I feel your videos help cover more of the basic, need to know topics that will be on the exam. Hoping my test in February has more of the topics in your video than the book! Thank you again, your videos have been lifesavers for me
I agree that the Mometrix ATI TEAS book can be overwhelming as there is a considerable amount of information in the book that you won't need to know for the exam. My goal for making these videos was to cover the foundational information you need to know for the exam without the stress of having to read countless pages. I am pleased that the goal is being recognized 😊💜 You got this, Valerie!! I am so excited for you to finish this test and get into your program.
Thank you so much nurse Cheung because of you I was able to pass my TEAS exam and can now apply to my program 04/17/24 😭😭😭❤️
That's fantastic news! Congratulations on passing your TEAS exam! 🎉 I'm so glad to hear that the videos were helpful for you. Best of luck with your application on April 17th-you're going to do great! Keep up the amazing work, and thank you for sharing your success with me. I'm thrilled to have been a part of your journey. Here's to a bright future in your program! 🌟❤️👩⚕️
Thank you 😊
Always Sharonda 😊💜
I take my test next Monday
That's coming right up. You got this!!
First of all, I LOVE your videos. I have watched all of the science ones so far as that is the area I'm struggling in and making lots of flashcards with your content to study. You really do break things down into the simplest form, so thank you for that! One question that I have is regarding meiosis II. I don't quite understand it. Do the steps begin with all of the phases of mitosis and then go into meiosis? In other words, does mitosis + meiosis II = meiosis II? (Interphase -> prophase -> metaphase -> anaphase -> telophase -> prophase II -> metaphase II -> anaphase II -> telophase II = meiosis II?) Thank you again for all of your help. You're a lifesaver!
First of all, you are incredible Tiffany Hughes 😊💜 Thank you for supporting my channel 💜 As for Meiosis, an easy way to think of it is that you have two stages of mitosis. The first stage is similar to Mitosis; however, the two cells that are created during the first stage are then split apart again following the same process leading to four new cells instead of just two.
Video is great but can you start drawing out more, it gives us visual learners a better way to maintain the information versus just talking like you're presenting a presentation. Thank you for helping us with the information you have created though!
Agreed
Thank you for your feedback, Taqueria Hines! I am glad you appreciate the video content, and I am working to make it even more helpful. I understand that not everyone will fully benefit from all of my videos and I tried to provide as many examples as I could in my video. Your suggestions will be taken into consideration. 😊💜
This is very helpful! Thank you nurse Cheung. =)
Thank you for the kind review Karla 😊💜
Test is days away I have faith🙏🏾🙏🏾
I am definitely reviewing this! I Know i will pass this test! Thank you Nurse Cheung! :) ❤
You got this Christine. I believe in you!!
thank you for your videos, they're a huge help! I wonder, will we need to do the genotype/phenotype charts on the TEAS 7 where we'll have to break down all flower traits?
Hi Carolann! Thank you for your kind words about my videos. They are a lot of work to produce, so I am glad they're helpful for you.
You will see a variation of the TEAS 7 genotype/phenotype charts for all flower traits. I always recommend that if one topic is a little too overwhelming, spend time focusing on the other topics within that category of the test so you can pass those and won't need the one or two questions regarding traits. Thanks again for watching my videos and being part of the Nurse Cheung community! 😊💜
thank u for the vids
My pleasure hambaby 😊💜
Last minute run through of your videos for my test tmrw. Super helpful! :) Thank you so much.
You got this, Lucy Nguyen 😊💜 Best of luck on your test today 😊
How did you do🙂
How did you do?
Thank you.
You're welcome!
Thank you
Welcome!
Thank you so much for these videos! Question why do the last 2 squares change?
Great question Laura Flores. Which specific part of the video are you referring to?
Can you do a practice video on blood typing and more punnet square problems for dihybrid crossing?
I'm glad to hear that you're looking for more practice in blood typing and Punnett square problems for dihybrid crossing! I am in the process of creating more trivia videos and I will include this in my upcoming videos to help bridge these gaps. I appreciate you and the feedback.
When you did the dihybrid cross chart and used foil method, I noticed you went straight across the top(left to right) then started from the bottom up for vertical side. Does it matter if i start from bottom up or go from top to bottom? Thanks for all you do nurse cheung!
In a dihybrid cross, you typically set up a Punnett square using the FOIL (First, Outer, Inner, Last) method to determine the different allele combinations each parent can produce. When filling out the Punnett square itself, the order in which you fill the boxes isn't critical, as long as each possible gamete combination from one parent is aligned on one axis (typically the top) and each possible gamete combination from the other parent is aligned on the perpendicular axis (typically the side).Whether you choose to fill in the gametes from top to bottom or bottom to top on the vertical axis, or from left to right or right to left on the horizontal axis, does not affect the outcome. The important thing is that each gamete combination is matched with each gamete combination from the other parent exactly once.
The goal is to be systematic in your approach to ensure all possible combinations are represented. This way, you can accurately predict the genotypic and phenotypic ratios of the offspring from the two parents in the cross.
if we were given a punnett square like the one at 34 min would it be given that they are looking for one type of inheritance over the other and that's how we determine the coloring of the chicken? or the opposite by being given the coloring and asked to determine if it's codominant or incomplete
Thank you for your question, Donya! We're sorry that we were not able to answer it in the video. The Punnett square is used to predict the possible genetic outcomes of a cross breeding two animals. In this case, we are looking at what color the chick will be based on the coloring of its parents.💜😊
I got a 59 on the science portion .. biology killed me !!! Did great in everything else but I still have to retake it again
Oh no. Thank you for sharing your experience with the TEAS exam. It sounds like you've got a solid plan for tackling the biology section next time around! I have no videos I am working on that will cover the Biology section much more in-depth, hopefully soon. We have lives every Tuesday and Thursday too to help answer any questions. 📚🌟
Hello, I had a couple of questions. I use the official ati teas 7 book to study. When I look at specific UA-cam videos talking about biology, they go in more depth than the ati book. For example, the videos go over dna replication( helicase, single strand binding, unraveling of hydrogen bonds) and different cell cycle( such as s, g1, g2 stage) that are not covered in the book. My question is that should I also be studying those things or should I stick with the official study guide book?
Hello! It's great that you're being thorough with your TEAS prep and noticing the differences in the depth of content between various study materials. The official ATI TEAS 7 book is designed to align closely with what you'll encounter on the test, providing a focused overview of the topics. Many test takers have advised that the TEAS questions are more in-depth compared to what is covered in most study guides. Which is why I created these videos to provide those more in-depth reviews.
Remember, the goal is to be well-prepared but not overwhelmed. It's about understanding key concepts well enough to apply them in various contexts, as the TEAS often tests your ability to think critically about the information you know.
Best of luck with your studies and your upcoming TEAS exam! You're taking a thoughtful approach to your preparation, which is fantastic. 🌟📚🔬📖
This really did help me get the whole concept of these areas since most of us had learned this in highschool. One question though, I have took the teas test and I've seen some questions regarding the whole membranes and transport processes like osmosis and diffusion! Will this topic be covered in a different video?
Great question Jazmine Aguilera 😊💜 Osmosis, diffusion, and cell structures are listed on the official outline for the ATI TEAS, so there is a chance you may see that content. Every test is slightly different but there is always a chance you could encounter it 😊
Yes even I have the same question
@Nurse Cheung can you share the link ... where we can refer this topics ... where we will get our concept clear
Can you please recommend a book to prepare for this and nursing prerequisites?
Great Questions Abena Saaba 😊💜 I would recommend using the books from ATI TEAS as they are going to provide the most up to date information on the current version 7 of the test 😊
Most of the questions on the actual teas are way more in depth than this but this was a good refresher
Hi there! Thank you for watching and leaving a comment. Yes, the actual TEAS exam can be more challenging, but it's great to hear that our videos served as a good refresher. Best of luck on your TEAS exam! 😊💜
Hey all , when you guys took the TEAS are the questions/answers similar to these or are they more scientifically written ? Thank you
Hey there! The questions on the actual TEAS exam may vary in their wording and complexity, but the concepts covered are similar to what you see in these videos. The TEAS exam aims to assess your knowledge in areas like English, math, science, and reading. While the questions may be presented in a more scientific manner on the exam, these videos provide a solid foundation and understanding of the topics you'll encounter. It's always a good idea to practice with sample questions and familiarize yourself with the format of the exam to feel more comfortable on test day. Remember to study and prepare well, and don't hesitate to reach out if you have any more questions. Good luck on your TEAS exam!
What does the V from ATV come from and the I from CGI at at 13:21
Ah, it seems like there might be a bit of confusion regarding the mnemonics ATV and CGI. These mnemonics are meant to help remember base pairing in DNA, where Adenine (A) pairs with Thymine (T) and Cytosine (C) pairs with Guanine (G).
However, the 'V' in ATV and the 'I' in CGI don't represent nucleotide bases or any specific aspect of codon attachment. They're just there to make the mnemonics more memorable or to form a pronounceable word. In the context of DNA base pairing, only the A-T and C-G parts are relevant.
It's important to remember that mnemonics are just creative tools to aid memory. The key takeaway is the pairing of the bases: A with T, and C with G. 🧬🔬🌟
Hello, I am hoping someone can help me out. I am going to be taking my TEAS 7 on March 3rd and I am freaking out. The ATI book was a waste of money and full of errors. I am going mainly off of Nurse Cheungs videos and researching topics like cellular respiration on the side. To anyone that has already taken the test, will this be enough material to study to get into low 90's? I only have one shot taking the TEAS so I appreciate any and all help! Also, chemistry and English (even though its my favorite topic) are proving to be my weakest subjects.
How did you do?
Do they make you right out the entire punnet square or is it pre filled?
Thank you for your question! In the TEAS exam, you may encounter questions related to Punnett squares, which are used to predict the probabilities of genetic traits in offspring. Typically, you'll be provided with the necessary information, such as the genotypes of the parents, and you'll need to use that information to complete or analyze a Punnett square. The square itself may or may not be pre-filled, depending on the specific question.
It's important to remember that the TEAS exam evaluates your understanding of genetics, including the principles of Punnett squares. So, it's a good idea to familiarize yourself with how Punnett squares work, practice filling them out, and understand how to interpret the results.
If you encounter any Punnett square questions during the exam, carefully read the instructions and the given information to determine whether you need to fill out the square or analyze an already filled one. Take your time, think through the problem logically, and apply your knowledge of genetics. Good luck with your exam!
Can the videos be used for the Kaplan nursing admission test?
Great question, Martina Corbett 😊💜 I am assuming you are referring to the HESI test that Kaplan uses. Unfortunately, while the tests are similar, their outlines and structures are not. The questions are relatively the same, but I can't guarantee my study guides will be enough.
i understood most of this except the punnet squares & the dominant/recessive alleles. it went from simple to very complex. can i ever be R before T. so many questions
Punnett squares can definitely get tricky, especially when you start dealing with more complex genetic traits! In basic terms, Punnett squares help you predict the possible genetic outcomes when combining the alleles from two parents. For each trait, an individual inherits one allele from each parent. If 'R' represents a dominant allele and 'T' a recessive one, in a simple scenario, 'R' would always overshadow 'T' if present. However, whether 'R' can be before 'T' depends on how these alleles interact in the specific genetic context you’re studying.
In the chicken punnent square.... why would the chickens be black and white? couldn't it be another option that they are a blend of black and white, so grey? how do you know if it will be incomplete dominance or codominance?
Hi Makayla, thanks for your question! 😊💜 Chickens can come in a variety of colors, including black and white. Incomplete dominance is when the two alleles (forms of a gene) for a particular trait are not equal in strength, so the phenotype (the actual appearance of the chicken) is a blend of the two. Co-dominance is when both alleles are expressed equally, so you would see chickens that are entirely black and white.
is there enough time in the exam to work out multiple allele equations
For genetics questions that involve multiple allele equations, it's advisable to approach them if you feel confident in your understanding of the topic and can work through them efficiently. However, if genetics equations are not your strongest area, it might be wise to allocate your time to other questions that you are more comfortable with and can answer accurately within the given time frame.
Remember that the TEAS exam is a comprehensive test, and focusing on improving your overall performance across all sections can contribute significantly to your final score. If you're uncertain about certain topics, it might be helpful to prioritize reviewing concepts that have a broader presence on the exam and where you feel more confident.
Hi at 22:04 I don't understand why it's not 25%?
Great question Nancy1204 😊💜 The question asks, "what percentage of offspring will have blue eyes?" Blues are considered recessive, and they are shown in the example as a lowercase "b." In order for an offspring to have blue eyes, they cannot have a dominant upper case "B" in their alleles, or else the phenotype will show brown instead of blue. If you look at the Punnett square, you will see that out of the four possibilities, there are two that have both "bb" alleles giving the offspring a better chance to have blue eyes. So in this case, the answer would be 50%.
Do you offer transcripts for your videos?
Thank you for your interest! At the moment, I don't provide transcripts for my videos. However, I do offer copies of my PowerPoint presentations on my website.

Omg I’m sooo confused with dihybrid cross! Why do we start with green in our squares?
I understand that dihybrid crosses can be confusing at first! When constructing a dihybrid cross, the order of the traits being examined doesn't matter, but one trait is usually listed first in the problem. In the case of the green and yellow pea pods, green is likely listed first because it's the dominant trait. When constructing the Punnett square, the dominant trait is usually listed first in the top row and left column, with the recessive trait listed second. This allows you to see all possible combinations of alleles and their resulting phenotypes. Let me know if you have any more questions or concerns!
@@NurseCheung thank you so much!
Wouldn’t the biological hierarchy start off with atom molecules then cells?
Great observation Julian Ruvalcaba 😊 The ATI TEAS Content Plan for Version 7 Breaks down the Biology Hierarchy as I have it listed in my presentation. Atoms and Molecules both fall under the chemical portion of the biology hierarchy.
@@NurseCheung thank you!
Is there a way I can print these slides out?
Hi Montre. You can find copies of my slides here: nursecheung.com/shop/ 😊💜
I am an international student and i have to give ati teas and concern about that is all the portion of these videos are enough if studied properly?
I hold a special place in my heart for international students as I used to work with them in my previous position extensively.
As an international student preparing for the ATI TEAS, it's great that you're seeking out resources like videos to help with your studies. These videos can provide a solid foundation and cover a wide range of topics that are typically included in the TEAS exam, which assesses basic knowledge in areas such as Reading, Mathematics, Science, and English and Language Usage.
While these videos can be incredibly helpful and cover a lot of the necessary content, it's also important to complement them with other study materials. This might include practice tests, study guides, and textbooks specifically designed for the TEAS. Practice tests, in particular, can be very beneficial as they help familiarize you with the format of the exam and the types of questions you might encounter.
Given that you're an international student, you might also want to spend some extra time on sections that could present more challenges due to language or educational background differences, such as the English and Language Usage section.
Studying properly, understanding the concepts, and applying them in practice questions will definitely enhance your preparation. Consistency in studying and taking care of your well-being during the preparation period are also key.
Best of luck with your ATI TEAS preparation! Keep up the great work, and don't hesitate to seek out additional help if needed. 🌟📚🌍

In prophase does the chromosome become visible or invisible?
Great question! In prophase, the first stage of both mitosis and meiosis, chromosomes become visible. This visibility is due to the condensation of chromatin into more tightly packed chromosomes, making them easier to see under a microscope. Prior to prophase, during interphase, chromosomes are less condensed and not as clearly visible. This change is crucial for the process of cell division, as it allows the chromosomes to be more easily separated and distributed to daughter cells. 🧬🔬🌟
thank u so much for this explanation@@NurseCheung
Do I need the extremely expensive ati teas study manual
While the ATI TEAS study manual can be very helpful, it's not necessary for everyone. There are many free or affordable resources available online that can help you prepare for the exam. Focus on understanding the core concepts and practicing with sample questions. Good luck with your preparation!
I take my test in 3 weeks I’m super nervous.
Oh, I totally get how nerve-wracking it can be, but you've got this! 🌟 Pre-test nerves are natural, especially for an important exam like the TEAS. Here are some tips and words of encouragement:
Stay Organized: Plan out your study schedule for these last few weeks, focusing on areas where you feel least confident. This structured approach can help reduce anxiety.
Practice, Practice, Practice: Use TEAS practice tests to familiarize yourself with the question format and time management. Review the answers, especially the ones you got wrong, to understand the reasoning.
Take Breaks: Don't forget to give yourself short breaks during study sessions. It helps maintain focus and reduces the feeling of being overwhelmed.
Day Before the Exam: Spend the day before your exam relaxing, maybe reviewing a bit, but mainly recharging. Don't cram. Ensure you have everything ready for the exam day, like your ID, any required materials, etc.
Exam Day: Arrive early so you don't feel rushed. Take deep breaths if you start to feel anxious. Read every question thoroughly, and remember that it's okay to skip and return to a difficult question later.
Remember, the TEAS is just one part of your journey. You've been preparing for this, and you have the knowledge and skills. Trust in your abilities and the work you've put in. 💪🌈
Wishing you all the success on your TEAS exam! 💖🍀✨ You can do this! 🙌🎉
I’m so confused about the dihybrid cross , please help😢
Dihybrid cross can be very confusing and is sometimes difficult to teach. 😊💜 I would recommend first learning the FOIL method so that you can master the first part of the dihybrid cross and then move on to the Punnett Square method. Once you have mastered both of those, it is easy to figure out the best of the cross, as the dominant colors or features will always be dominant. You will need to configure what the possible traits are at the end 😊💜 Best of luck Meami. You got this!!
When you say to multiply, what are you multiplying? I don’t understand how you are getting the answers to fill in. I understand the foil method though.
I don’t feel like I would do good at this part 😩
Hey there! I understand that it can be tough to feel confident in all areas of the ATI TEAS exam. But don't worry, you got this! With practice and dedication, you can improve your skills in any area of the exam, including the part that you feel less confident in. Don't hesitate to seek out additional resources or support if needed, and remember to take breaks and practice self-care along the way. You can do it!
This one and chemistry scares me lol
Don't worry, you're not alone! Many people find Life Sciences and chemistry intimidating, but with practice and a good understanding of the concepts, you can do well on the ATI TEAS exam. Keep watching educational videos and taking practice tests to build your confidence and knowledge. Good luck!
The explanations of the Dihybrid Cross is confusing. Would of been better explaining why you picked the Big T Big T Big R Big R. Would prefer you explained why you chose these.
Bread & Beer, no Cheese because you are Vegan lol
I am a vegetarian and I don't drink alcohol either but yes I do love some bread 😊💜
Hello nurse Cheung!
I guess I'm stupid because I'm having a real hard time comprehending the definition of OSMOSIS. Two definitions show up on Google; "osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules", and "water moves from areas of low concentration of solute to areas of high concentration of solute."
So, is it High to Low or Low to High?
Are they pretty much mean the same thing since one is solution and other one is solute.
Thank you so much in advance for helping with my stupidity :(, and have a wonderful weekend!
Hello there! Don't worry, you're not alone in finding the concept of osmosis a bit tricky to grasp. I'm here to help clear things up for you.
The definition of osmosis can indeed be a bit confusing because it involves both the movement of water molecules and the concentration of solutes. To simplify:
Osmosis involves the movement of water molecules from an area of low solute concentration to an area of high solute concentration across a semi-permeable membrane.
So, both definitions you found are referring to the same concept, just phrased slightly differently. One mentions the concentration of water molecules, while the other focuses on the concentration of solutes. Remember that osmosis is driven by the goal of equalizing the concentration of solutes on both sides of the membrane.
You're not stupid at all! Understanding these scientific concepts takes time, and you're making the effort to learn. Feel free to ask more questions if needed, and have a fantastic day!
