THANK YOU SO MUCH! I've been using your videos all throughout my GCSEs and now my A-levels. It's nearly impossible to find exam-board specific videos that cover ALL topics in depth and your videos come in so handy when I don't have the energy to be writing out hundreds of flash cards the night before an exam.

Module for AS and A-level:
module 2-foundations in biology : 1:59
module 3- Exchange and transport : 2:24:26
module 4- biodiversity evolution and disease : 3:18:09

Module for A-level only:
module 5-communication, homeostasis and energy : 4:26:51

[ineffablefallen]

thank god for these. straight up panicking because of the exam tomorrow being in the afternoon after another exam i have in the morning. all hail primrose kitten

[mohammedsultan]

Hey, could you post the OCR A level biology paper 1 predicted topics please

[alicemaryomomowo]

i dont know how im going to get through all of this by the end of today. im really panicking!!!!

[huzaifa]

I think you’ve made a mistake and mixed up noradrenaline and acetylcholine around 6:26:00

[harrymead]

What do we reckon all this in a week? Possible? Idk y i took biology

[iitslynx]

paper is tomorrow, i am cramming, thank u <3

[theeviperx]

Do you have video for math skills/ practical skills in biology, like standard deviation, null hypothesis, that type of stuff?

[shhhxo]

could you draw out a relevant diagram for a question if you struggle to explain well? for example if a question was something to do with amino acids and urea production could draw out the deamination and ornithine cycle/or a question about the action potential steps could you draw out the graph and label depolarisation and repolarisation and stuff and still get enough marks?

[preciousemmanuel]

thank you so much for this video! is there anywhere I can access the slides you used in this video?

[KeiraSmith-dt]

This is amazing - would you consider doing one for a level educas geology - there’s no textbook and my lecturer just tells us to google the answers :(

[ForevsGlamourGirl]

Will you be doing an A level AQA chemistry video as well?

[slapmynutz]

already putting paper 2 on packwatch a day before the exam💀💀💀

[MA-phzg]

hello miss I had a question, I wanted to get A level subscription so i wanted to know would I be able to access both biology and chemistry ? and would you do predication paper for AQA a level chemistry paper 2 ?

[oshovarman]

Can someone comment the timings for each chapter in this video it would be helpful!

[amy-ypkt]

Please can you do the whole of eduqas a level biology?

[maellepaih]

The Kidney section was the longest thing of my life istg
