At A2 (on the old spec), there was a bit more maths involved. We had to be able to understand natural logs and exponentials (which I learnt in A2 maths), but like others have said if you can rearrange a formula, use pathagoras' theorem correctly and work out gradients of graphs seeing as there's always one question in an exam asking you to do so, then you should be fine on the Maths front. Those three concepts are pretty much GCSE level Maths tbh so you shouldn't worry too much. Physics was more 'explain in words whats happening here' rather than 'calculate this and use it to prove that this is so'.
