Biology, chemistry and history for medicine?

Hi yall,
I just started AS and im already thinking about what to drop at the end of the year (which is pretty early on but im a big worrier lol)
I'm taking bio, chem, maths and history. Lots of people say that I should drop history because it's an arts subject and I'm fully aware that it could reduce the amount of med schools I could apply to, because some ask for maths. However, I really, really enjoy history and I feel like it would give an interesting variation which is beyond the standard med a levels. I do also really enjoy maths (also got an a* lol) but I feel like my history teachers would love me to carry on history because I was the only one who got an a* in it.
What schools would accept, even prefer an arts subject coupled with 2 sciences? (I know UCL is one, apparently) Which ones prefer maths?
Or should I just stop worrying and wait until I progress through the year and see which one I'm better at?
