Is it a bad idea to pick CS, Maths, Further Maths and Physics for A-Level?

I want to do something to do with Computer Science in the future, and I believe it is also a requirement to take Maths at A-Level and is recommended to take Further Maths. I am taking Further Maths for GCSE, and overall it’s not that hard, but I’ve heard a lot of bad things about A-Level. With my last option I wasn’t sure, but I was thinking maybe Physics? It compliments math well, but at the same time I’m not sure if I’m going to be able to cope with that much maths. Also, are there any other subjects that might go well with CS, Maths and FM?
