English Lit isn't demanding at all. Just ensure you attend all the lessons and then do all the reading. Tbh, you have to read like 3 books in AS year and 3 + synoptic (unless that's changed) in your A2 year so like, that's not really hard.
Chemistry is way better than Biology but then again they kind of go together well...I'd probably say take both and drop Further Maths or something. But you seem quite Mathsy and Chemistry/Physics/Maths/Further Maths is a popular combo. (Biology is a bit easier, yes, but maybe not with your combination).
