im sitting my a level physics exams this summer and im hoping to do physics with astro at uni next year. dont get me wrong, it is a pretty hard subject, but if you enjoy it, especially at gcse its manageable. personally, the content in year 12 for me was much harder than yr 13 content and most of it is just additions from gcse concepts. if you are thinking of taking a level physics, definitely have a good think of the other subjects you will take alongside it. i take physics, maths and computer science and i must say maths is super useful to have for physics. the exams itself arent too bad, personally i hate forces so moments are a pain but its mostly just applying concepts using the formulas that are in the formula book. the hardest bit i will say is paper 3 which is applying physics to concepts that you would not have learnt at all and applying physics to real life, this paper is pretty tough but it does get easier with just tons of past paper practice. for context, i got a 9 in gcses (2022 so covid grade boundaries) and ucas predicted for uni a* in alevel but currently getting a/b so it is alot of work haha. but if you enjoy it, it can be a great subject for a levels. i hope this kind of helps hahahaha
