Bio a level if i’m bad at chem

basically asking how much of biology a level is really chemistry. I haven’t done any chemistry revision and I probably won’t do much at all because I’m so bad at it there’s no hope.

so is it a mistake to pick biology for a level? I’m good at it at gcse, getting an 8 and hoping really hard for a 9, but everyone says there’s a lot of chem is biology a level. is it basic stuff or more complex?
