4 A Levels, 1 unrelated

tbh i like biology but not that much, but i want to do it at a level coz loads of courses have bio and chem together and i dont want to limit everything. i really like chemistry though and maths is pretty cool, rs i just find really interesting and want to learn about it.

but what if i decide to do biochemistry or something and i need biology. i kind if overthink it. the load of conetent in biology is kind of off putting but everything has to do at least 3 a levels and im not getting anywhre with rs,, since i am only picking it for fun

i dont think ill have any problems with chemistry and maths, but biology. ii think im already slightly disliking it coz everyones saying theres loads of content (there is)

yeah i think the tests in the first year is to predict our scores in our final year. But im wondering, do you have to decide if u want to a subject at as or a level when you choose it, because the content is different for them both (like as is more than half the content in a level)?
