First, let me apologize for my bad English, it's not my native language. Most areas of math for me aren't really an issue. I'm actually quite good at it. But there's one thing I absolutely despise and also something I'm very bad at: geometry. I was planning on studying theoretical physics, but after seeing how horrible I am at geometry, I've started to have doubts. So you could tell me, how important is geometry for someone who wants to study theoretical physics? And is it possible to improve my geometry skills by simply practicing a lot? Also, is applied physics very different from theoretical physics, when it comes to math?
