In a slight diilema

So, I picked up my AS results last month, I got good grades, therefore I will be continuing with A2. I did 4 subjects at AS, however it is sort of expected that you should drop to 3 subjects for A2. I told myself at the end of the year I would drop the subject I got the lowesT grade in, which turned out to be History. However, I want to do History at university, and I really don't want to drop it, however, I don't want to drop any of my other subjects either. I also feel that if I carry on with History and my grade does not improve, I fear that it could stop me from getting into uni altogether. So yeah, I'm abit confussed as to what I should do.

Oh, and incase your wondering, I got a B in Business Studies, C in Law and English Lit and D in History.

I'm also aware that I've typo'd dilema.
