Best subjects to become a Chartered accountant

Im currently confued on the subjects to pick for A levels.
The subjects i have listed are avaialbe for me to choose regarding my gcse results.

Economics
Law
financial studies
sociology

What would be the best and strongest subjects to pick out from the list?

I suppose here, the question is: what A Level subjects are best to get into a degree that will allow me to become a chartered accountant, seeing as you'll most likely have to go to uni first before you can become one.

If so, the best degree to do would be Accounting (or Accounting & Finance).

Thus, at A Level, I'd say the best subject combination is Mathematics / Economics / Accounting.

From your list, definitely do Economics, then Financial Studies, then law.

Is math not an option?
