Are these ok A-level choices?

No. I dont know any course in any university that says its essential to have geography so its not a good choice for keeping your choices open. Swop it with a science. Infact the most open a-level combination would probably be something like Maths Chemistry Physics History. You can study dubjects from engineering to medicine to most BA in lower-mid tier universities

Physical Education?

I'm vouching for Geography on this one. I absolutely LOVED doing geography at A-Level (I'm on my gap year now). I don't regret taking it at all, I learned so much and it genuinely gives you a whole new perspective and depth of understanding of such a broad range of subjects that you study, as well as really encouraging independent learning.

However your choices really depend on what you want to study later on, but at the university open days that I attended at the end of L6 - all of them really good unis - I was worried about my choices but the admissions staff told me that as geography is an essay-based subject it was a good choice for A-level, especially if I wanted to go on to do an essay-based course, which many of them are if you're not doing the whole science/maths based route (and even, then I think).

I think doing maths as well gives you a broad subject range which is always a good thing. I really can't comment on History, the teachers were crap at my school I didn't take it.

Most important of all, do the subjects you have a genuine interest in, especially as you'll be studying and writing about them non-stop for the next year, it really helps to be passionate about your subject.
