Honestly thank you so much because I just got 84 % on a test which is the highest I’ve ever gotten by watching your videos
Wow!!! Congratulations that's amazing ☺️☺️☺️
Hi, do you use the entire topic vidoes as a revision resource or the individual lessons?
ooo congratulations!! 💓
Similar - I got 89% and 74%
I've been using your *entire topic* videos since September this year, and theyre sooo helpful like for revising content (im walking to school watching this in 2x speed LMAO) thank you miss, you are such an angel lifesaver ily 💓 thank you for taking the time out and putting effort in to create these videos, they're SO helpful ohmyogsh 💗💗
Haha that's an awesome use, great multitasking. So pleased you are finding them so useful 😀
Got my Oxford AQA A level exam in an hour and a bit. I have to thank you for all your Unit 3 help 🙏
Your videos helped me grasp all the concepts and memorize them, allowing me to then work on exam technique. Thanks!
Good luck!!!
Got my a level biology eduqas exam tomorrow, but a lot of this content is on my paper tomorrow except the Phosphorus cycle as it is not on our spec. Instead, microbiology is on paper one, wishing every one of us luck tomorrow for every exam board! Great Video!
24:15 I think there should be brackets around the F + R, so it's N = I - (F + R)
I dont think it matters. For making it a bit more understandable it does but if you follow the rule BIDMAS, it doesn’t matter.(Brackets, indices, division, multiplication, addition, subtraction)
@@sifnatdavid6306 It does, you're not adding respiratory losses, you're taking them away. That arrangement looks like you have to add the respiratory losses.
@@sifnatdavid6306 BIDMAS doesn't quite work like that, it's more like BI(DM)(AS), the addition and subtraction are on one "level", so you do them in the order the expression says. You can test it out with your calculator! If you put 5 - 3 + 2, you should get 4, but with 5 - (3 + 2) you would get 0. So the brackets do matter quite a lot in this instance~ hope that helps 😃
Yes now thanks for all the amazing vids, gonna watch this now
Yes!!! Hope it helps
I love you so much!!!! you're a lifesaver... quite literally!!!!
haha so pleased it's helping 😄
Hi miss @21:03 shouldnt it be oxidising reduced NAD instead of NAD?
The pain when your native languages isn't English, so you have to translate everything 🥲
@@heeseungpuffs7897 ohmygod thank you hahahaha ((;
AHGASE??
I fell your pain
thank you so much these videos are perfect for revision!!
Yay!!!! That's exactly why I made them so I'm really pleased it's helping
please can you make a video where you go through possible calculations we can get for energy transfers and ecosystems ?
On Topic 2 which are Cell structure and division, cell membranes
Thank you so much!
You're welcome 😊
Thank you! 😊
You're welcome 😊 I hope it helps.
do we not need to know about non cyclic and cyclic in the ldr?
Dear Miss, during the Link Reaction should we mention the decarboxylase enzyme if we`re asked a question?
if you were asked how the carbon dioxide is removed it would be relevant
Thanks for the great video. I was just going to ask you whether you could place all the subtopic videos in each topic playlist in the order they appear in the Spec?
They should all be in order already. Which playlist have you spotted that needs arranging?
@@MissEstruchBiology
Thank you very much. For AS, Topic 3 is not arranged. .
For the Calvin Cycle do we have to know the full name of each molecule or can we just write the short form in the exam? For eg. "RuBP" instead of ribulose diphosphate. Thanks :)
i think we can write the abbrivation x
Hi miss what are the numbers for the etc
Another video finished during (and after) breakfast XD
Smashing it!!@
Thank you so much these videos are so helpful! would you be able to make past paper walkthroughs please ?
I'm starting my new exam questions series in January!!!
Thank you so much i look forward to watching them🥰❤so much@@MissEstruchBiology
I know these videos are in line with the spec, however how much would you say isn't included and would require me to review the textbook? I am trying to make flashcards and don't wanna miss anything
it covers the entire spec, but my full videos give full explanations. For flashcards, testing key concepts, it should be sufficient
@@MissEstruchBiology thank you so much!
quick question I am a little unsure if for aqa do we need to know about hexospbisphospate?
Pretty sure it’s a no, check the spec tho!
could you make one for topic 4 please
Yes! Topic 2 is next and then 4 ☺️
Thankyou so much!!!! Waiting on topic 4
How can i get the notes
hey heres the link missestruch.co.uk/product/a-level-aqa-biology-notes-full-set-topics-1-8-copy/
During the stage of Glycolysis where 2x triose phosphate molecules are dephosphorylated and oxidised into 2x pyruvate, how can 4 ATP be regenerated per cycle if there is only 1 phosphate group on the TP?
per glucose im guessing
yk it’s the morning of the exam when ur watching in 2x speed😫
Fr good luck 🤺
Good luck
What did you get?
