i just had to comment and tell you that you’ve helped me get my bio grade up from D/E to an A/B and now i’m able to apply to my top choice uni cuz i actually have the grades now😭thank you so much seriously you’re a lifesaver
Yo, i just binged all your AS videos just to remind myself for the upcoming autumn exams and must say - you really do follow the spec to a high degree! For me miss estruch was the best resource for biology- but you’re on par with her! Absolute blessing - thank you
It's very unlikely that you will be asked to calculate standard deviation in an exam (just interpreting results of it), but they would probably give you the formula. I would memorise it though just to be 100% safe!
