For a while now I've known that I would like to do theoretical physics, but I'm having trouble finding out how hard the maths involved actually is. I would like to study this a Trinity College, and on their website the minimum requirements are a B2 in higher level physics (no problem, I can do that), and the same in higher level maths. Problem. Now, I'm definitely not bad at maths. I got 68% on my Christmas test, and most of those mistakes were due to me panicking in the exam situation, and when I redid the questions afterwards for homework I got them all right. I got 85% (A2) on the physics exam though. So, what I really need to know before I make any decisions is; how hard is the maths?
