No idea what course to do

I’m doing AS Chemistry, Biology, English Literature and History. I’m pretty sure I’ll drop one subject for A2 next year, I was originally planning to drop History but I’ve found Chemistry kind of boring so I may drop it instead. The main problem is I’m really interested in things like biochemistry, biomedical science and microbiology but I’d have to commit to another year of chemistry. I’ve also really enjoyed English and History this year, I love public speaking and I’ve looked at courses in Communication, Advertising and Marketing. These two areas are so totally different and I really can’t decide between the two, please help if you can!!
