I do not know which subject to take to A-level, either Maths or Physics. This will be my third subject, with Biology and Chemistry. Which one is more similar to GCSE? I got an 8 in both, but need an A or A* so I do not know which is best for me. I enjoy learning Maths more than Physics, but do struggle in Maths sometimes.
In physics, you'll study many of the topics covered at GCSE in a bit more depth whereas most of the stuff you'll cover in the maths is brand new. You should choose maths. The three subjects combined will meet the requirements for most science courses when applying to university.
