@“Snowball City”:
No. 3-5 AP’s with mostly/all 5’s in them in relevant subjects can get an American in to pretty much in to any UK uni besides Oxbridge (which have their own harder tests and an interview) and LSE (too much demand for slots).
However, A-Level Maths and Further Maths definitely cover more ground than just AP Calc and AP Stats (it’s annoying that, just because it isn’t in AP, most American kids don’t learn stuff more useful to more people than calc like numerical methods).
