Chemistry or Physics A level

i got an A in chem, A* in Physics but I was capable of an A* in Chemistry

Planning to do Chem atm but not sure whether to change
I dont really know what i want to do in the future but something in the science/forensics route

I choose Chem because I think it can open more doors to courses for me and if I decide I want to do medicine or something like that i can do it but I do like Physics however, everyone tells me that physics a level is super hard.

Im currently doing biology, chemistry, maths and psychology and the only one i think i would change would be psychology dont feel like changing to do 3 sciences cos i dont think i can do that so im thinking either physics or chemistry

any advice??
