💁♀️ HI I'M MELISSA MARIBEL
I help students pass Chemistry and Organic Chemistry. I used to struggle with this subject, so when I finally graduated with a bachelor's degree in Chemistry, I became a tutor so that you wouldn't have to struggle like I did. I know that with the right help, YOU CAN LEARN ANYTHING!

you are my savior!! My chem slides didnt even mention this part and im paying nearly 1k for this class. Thank you for helping other students especially during this pandemic where having a one on one with a professor is difficult nowadays.
Jesus Christ is our Saviour
Need to find a better class I am sorry yours is bad.
Ikr!!!!! I have a short test on these tomoro
This was SUCH a big help!! Thank you so much!!
I'm sad that you don't have more views on this! Everyone needs to watch this video!
You're an amazing teacher, thank you very much for helping us all! :)
Omg I can understand this more easily than my teacher's explanation. Youre a life saver! Haha
Yea
Me too✨✨
I commend you Melissa. I've never seen a youtube tutor take the time out to work with other people. You've definitely taken it one step further. And, in the process it helped so many more.
you've made this more clear. Thank you Melissa
Thank goodness for you! Helped me SO SO much! You are definitely one of the best tutors on UA-cam!!
Thank you so much for doing these! It is like getting one-on-one tutoring, and your student asking questions and you including your answers helps so much more than just someone talking at me the whole time. It is so nice. This is a lifesaver find on the internet for me!! xD
thank you!
This kind of video set-up is super helpful! Thank you Melissa
I can't believe this is free to watch, thank you so much!!!
Some great stuff! very easy to follow along, thank you very much!
A very perfect way of showing the student solving the problem and as the student moves on, giving instructions. My students learned a lot from that. Not many have a youtube whereby the student is active solving a formula. Very very very good. compliment.
Hello Melissa, this video really helped out. Thank you!
This was a HUGE help for my incoming exam!
Thank you so much!
Love from Italy
THIS MAKES SO MUCH SENSE NOW THANK YOU
I just found this video, THANKS! I wish i had a teacher like you, you are awesome!
You saved my life!!! Thank you!
Thank u very much, that helps me alot, this is the first time i understand why there are more than one Lewis structure for polyatomic ions.
I got all of it just right. Thanks!
This video helped me SO much!!! Thank you, thank you, thank you!
Video was so helpful! Thank you!!!!!!
It always takes me so much time to get myself to sit down and actually study for chemistry and you always help me in completing my studies. Thank you so much!!
I literally have an exam today and this just saved me. Thank you!!
You are AWESOME! Having a student sitting in was super helpful, too! College life saver
thank you so much I went back to the uni after 3 years dropping off and was forgetting all the chemistry I learned back in high school, this helped me a lot. : )
These are brilliant thank you so much, you have no idea how much youve helped. and you explain everything so well
Thank you so much. I just found this one when I am very stuck with Lewis structure
The notes are so pretty I can’t stop looking and by extent I’m actually learning!
A great tutorial....students usually have problems with octet and expanded octet and fc....but the explanation was great...well done and thank you
so freaking helpful, thank you!!!💛
You're the best!!! You literally NEVER fail me :)!
Thanks a lot for the video .This was a great help for my studies.
THIS VIDEO WAS A LIFE SAVER OH MY GOSH TY
You are THE BEST! Thank you!
I'm so greatful, you helped me with my chemistry exam next week...
Melissa, you put in a lot of sincere efforts in preparation and lucid teaching.. Kudos..
Thank u sooo much , it helped me a lot !
It's very helpful 😍 it would be great if you could give more practice problems, thank you so much!!
This is so helpful, TQSM!
Thank you... I have just finished my quiz successfully. Since now, I am your new subscriber.
Thank you so much✨✨
I understand much more💕💕
Thanks, I have better understanding for formal charges after watching your video.
You are really amazing 🎈 my way to chemistry has been made easy by you....God bless you ❤️❤️❤️I love you
This helped me so much!
Everything made sense ma'am you are amazing ❤️❤️❤️❤️
Thank you soooooooo much!!!!!
Have really understood wooow so happy thanks mrs
Really helpful 🙏🏼♥️
I really like these kind of problem solving videos
Using this adding formula instead of the fraction formula is so much easier. Thank you.
you are amazing thank you for saving me from my college complicated assignments.
SUCH a GREAT help Thanks
Melissa, I grew up in a cult where we weren't allowed to learn Science at all. I recently started college and was terrified of how I'd do. Over the summer I watched all of your videos to prepare and I just took my first Chemistry test ever and got a 95%. Thank you!!!!
wow
I am from phillipines and an I.E student from pup, thank you for having a detailed discussion about this topic especially now a days, we're just finding our own way to learn by ourselves and tbh, it is really hard.
I'm sure with this, I'm not failing my tests. Thank you so much... I can't believe I fully understand what has been giving me headache, I'm so teary right now
Extremely useful video for my students. Make more on other topics also !
This shit is the best, rarely you see vids that tutor, keep going you goats, also nice editing, love how much work you put in!
this helped a lot...thank you
SO HELPFUL.
GOD BLESS YOU OMG I'm taking summer gen chem at my community college rn and its been so stressful the professor barely has time to cover everything so she had to rush through this unit and I was honestly trying not to cry on the way home 😭 watching this video definitely cleared up a few things for me and I'm feeling a lot more confident, my exam on this is in 2 days
i think i need a little more practice and ill be where I need to be to get that A !!!
i do not know how you don’t have more views, you are fantastic!
You are a great teacher 🤗
Thank you! have my finals tomorrow.
Really you are so good your explanation is very very good and when you was teach I just kept looking at you honestly you are so good teacher and my guide
That's amazing thank you so much
Melissa is the best teacher I have ever met. Thank you so much for making the effort to change our lives!!
Never would've thought watching this kind of tutoring videos would help me understand something better!! that's it, gonna go for "with us" rather than "with me" from now on
I really get to understand chemistry watching your videos
You like 💯 Amazing
YOU ARE A STAR !
so helpful!
U are truly a savior 💯💯 I love u❤️🥰
I have a chem quiz tomorrow on Lewis Dot Structure and I was super worried about it, but now I'm not worried at all. Also, I never comment on youtube videos but you are such a great teacher that I had to say thank you!
Thank you so much Maribel !!! please keep posting more for OChem. I am learning more with you than with professor.
You always help me
It would nice to have an OCHEM basis video.
i was like genuinely clueless about lewis structures but now i have such a clear understanding of them that's crazy
thank you!
Thank you for your content! It has been very helpful!
I actually am confused about the very last problem. Why wouldn't nitrogen and oxygen have a double bond and then fill in the lone pair for oxygen? When do you use double bonds versus lone pairs?
thanku mam it helps a lot
Thank you so much
Their is a trick I got from this whole lesson
That is ,that when their is just a single minus sign that means I will have just one single bond in the structure and that also implies to the sign of minus 2
Thanks for this great video
Thank you so much mam
you're awesome!!!!!!!
Your formal charge equation I prefer over the book! Thank you so much I understood it better practicing with you.
Melissa the wise giver❣️❣️🕊️🕊️📝
Love u Melissa ❤️
Please upload a video on acids and bases,my favorite teacher
gracias!!
You are the best ❤❤❤❤❤❤
Awesome!
Thanks!
I cannot thank you enough!!!!😭😭😭😭😭
it was good..
HIIII Melissa, I just wanted to ask if it matters where we put the hydrogen for the oxygen in the last problem?
احسن من شرح دكتورنا
Can you make a video about functional groups? PLEASE AND THANK YOU!!!
Thanks from India mam
You’re the best
Thank you for all of your help. At least I was able to pass my Chemistry class. May God bless you and your family. Stay safe and well. Enjoy your summer as well.
Thank you melissa it was really helpful!!❤ i could nt understand one part at 24:48 why one of the Fluorine atoms have only two lone pairs i understand why the other Fs have 3 lone pairs but i don t get why this F has 2 lone pairs
why is it more favourable to have a neutral formal charge on the central atom? do you have a video about this?
This is so helpful! I was forced to take a chem class with this kind of stuff in 7th grade, and seeing Melissa Lucy (who is way older than me) doing this stuff at her age made me kinda stressed. But after seeing this video, anybody can make Lewis structures with formal structures with a little practice. Thx Melissa for another great video :D
any have an idea why the last question at 27:50 can't have a double bond between the Nitrogen and the Oxygen with the Oxygen having 4 electrons on it still
