All sciences and geography is a great combo, they go well together. Which one were you thinking of dropping at AS?
As to courses, with these you'd be pretty much okay for any science course except maybe physics (that kinda needs maths), you're good for medicine, geography, geology and other subjects like that.
I get that you don't want to do maths, but physics can be incredibly tricky sometimes without it and anyone doing physics without maths has to go to special 'physics maths' sessions at lunch at my school. Some topics are okay, but at both AS and A2 there are a lot of bits that are much harder without maths, or that use types of maths such as integration and natural logs that you really will need a few maths lessons for.
