AQA Bio, Chem & English Language

I did bio and chem at A level but I did OCR so I don't know how much difference there is. I'm currently studying medicine so I really enjoyed both of them at A level. I think it is a good choice - I know quite a few people on my course who did a similar combo (bio,chem, eng lit) so I think they should work well. I would say they are manageable but obviously, they will require a lot of work - a few of my friends did english lang and they got set quite a lot of essays to do.
For my spec, the bio exam mark schemes were super specific which makes them pretty difficult to score highly on but the grade boundaries were about 70% for an A*. Chem exams were a lot easier but you also needed almost 90% for an A* so it kind of works out the same.
Bio has more content than chem but chem has slightly harder concepts and still requires a lot of memorisation. Chem also has a fair bit of maths so you might need to put in more work to understand that side of things (I did maths and it helped a little but by no means do you need to have it)

Thanks for your response! I can confess that I am slightly worried about the content for A-level bio as I didn't manage to finish the spec in school (I did separates) and also know that there were parts of it I hated (but I guess you get that with all subjects). Also, I constantly hear people saying the content is huge but I'm hoping I can manage it if I start making notes at the start of year 12? Also, I have been thinking about the maths content lately and whether or not I'd struggle with it without studying core maths or A-level maths alongside it but a few people have said I'll be fine as the maths will get covered in the chem lessons. I'm mainly taking bio and chem in case I decide to go into pharmacology/toxicology which really interests me. Do you have any tips for A-level Chem and Bio?
