LITERALLY LEARNT MORE FROM THIS THAN I DID FROM 5 MONTHS WORTH OF ONLINE LESSONS. THANKYOU SO MUCH!!!

[aaliyahpatel]

OMG YES! FINALLY! I’ve been waiting for these for so long! I can’t wait for the others- your videos are AMAZING!

[annawallace]

Hey, just dropping in to say thank you! I am a 30 year old lawyer who has decided to career change. I am studying A Level Biology and Chemistry in preparation for my Pharmacology degree (with foundation year) starting in September. I'm going to go into biomedical research... You're helping such a broad array of people, so thank you! <3 x

[fountainofknowledge]

YOU ARE SO INCREDIABLE 😭😭😭

I started studying with your videos maybe 2/3 years ago for gcse science. I went from a D to A student in the space of one year...
Now that i'm studying A level Biology, i cannot wait dive into these lessons, THANK YOU SO MUCH!!

[amya]

i used this queen for my gcse’s and now she’s doing ALEVEL YES YES YES THANK YOUUU

[whomerdoodles]

I just made 23 full pages of detail on the whole topic, thanks to this.

Thanks!

[jasmine]

this is perfect timing, i have 2 biology mocks next week on AS things and i literally searched for this on friday!

[bluearmy]

Please do A level Maths Statistics and Mechanics next

[novelupdator]

Havent even started the content in lesson yet but im making a headstart 😁

[tomlawton]

This is excellent. I'm studying outside of any college so this sort of material is invaluable. Please continue the series (and stay well)!

[kingmuizz]

Good luck on Monday anyone doing that exam!

[mayadahele]

I got an 8 and 9 in my GCSE science thanks to you!

[moguanshan]

did she also do cells ?? this is awesome thank youuuu

[laranja]

Thanks to you went from an u student to an a student during igcse, you saved my life

[emmatomlinson]

Thank you so much!! Now I might actually have a chance at passing😂😂. Could you do one for AQA A-Level Chemistry??❤️🙏

[BELLE-yl]

Please do more of these videos. I love them and you make them so easy to understand. Currently I’m struggling with all the content especially section 3 and exam questions

[diamond-zbrl]

Can u do this for OCR A level biology please thanks!

[riyapatel]

Please do a level biology edexcel b specification soon!

[itsemilyxox]

hi! your videos help me so much! you've probably already been asked but i'm really hoping for an OCR A Biology A Level video!! Would be life saving!! I understand it's probably so much work though! I'll have to keep checking haha!
