A-Levels

Is 4 A-Levels too much for someone who’s currently foing 10 GCSEs and predicted all As and A*s? I’ll definitely do Maths and Physics but for option 3 I’d do business or French then for 4 I’d do RE or Sociology. If I was picking three I’d do maths and physics then one of the listed 4. All under ccea I think? Anyways thoughts?

4 A-Levels confers you no advantage for uni applications, other than risk bringing your grades down. You sound like a very capable person, but A-Levels are harder than GCSEs and so it's a bit of a gamble with your grades. Unless you want to take four because you love all four and you really really really want to learn about those subjects, then I wouldn't do it.
I took 4 A-Levels back in my day. It was a bit of a cheat, because one of them was my mother tongue, but even then, that meant 4 hours less a week to do work at school, plus an extra subject's homework and study (I still had to work for the language and commit to memory a fair bit about literature and cinema!), and while that translated in a not too shabby set of A-Levels, honestly, it has done absolutely nothing for me in my life post sixth-form, and I could have just saved myself a tiny bit of troubles and stress in sixth form.
