For those who did Physics years ago, it has changed a lot. They took calculus out about 10 years ago and broadened the syllabus massively (inevitably removing some depth).
Make no mistake, it is still a ‘hard’ A level, by some measures the hardest, but not in a mathematical sense.
So, I would say that, to do Physics, you have to really like Physics and Maths, especially the problem solving elements, but that does not mean that you have to do a Maths A level. The extra Maths, over and beyond GCSE is, off the top of my head, logs and exponentials and a deeper understanding of trig (a couple of simple trig identities and small angle approximations).
What a previous poster said about the two being a natural fit it true. But, on the other hand, for medics especially , the 3 sciences are a good combination.
But….you really have to like it, not choose it because you got an 8 at your GCSE. A level physics, whilst nothing like uni Physics, is still a step change up from GCSE Physics and, if you aren’t prepared to persevere when the going gets tough, you will come a cropper.
In my last year of teaching my best student, who got an A* on a tough paper, was a medic who wasn’t doing Maths, but that doesn’t mean he wasn’t naturally able at Maths; he definitely was. And he was prepared to work really hard.
