Will A level physics be too hard for me? Watch
However, from the predictions you have shared, I think that you will be more than capable of doing well in A Level physics.
You are well qualified to take A level physics with a B in GCSE, especially with an A* in maths.
Remember it's just a prediction. It's not too late for an A*/A and even if you do get a B, you have the entire summer to brush up on your physics if you wanted to.
Your mathematical ability will definitely help with AS physics too, and mechanics part of physics will overlap with maths M1 module which makes it easier.
I don't know if it's still the chemistry vs physics for you but anyway don't worry too much and focus on your GCSE now. You have the entire summer to worry about it and most of the time school will let you change after deadline
