Right now, I've only really done physics for two months, and despite getting a top grade at GCSE, there initially is a big jump from GCSE to A-Level. Sixth Forms will keep telling you that about all subjects, and it's really true for Physics, more so than the other Science subjects I'm taking, along with Further Maths. A lot of it is quite easy to wrap your head around, but when it comes to the calculations, the wording of the questions have gotten more complicated and confusing. Other than that, the subject has been quite enjoyable, and if you really love the subject, you should take it.
