Further Maths choices

So I'm taking a year out and reapplying to university. I am going to study AS and A level further maths in my spare time as I can take the exams at my old sixth form in the summer. I'm uncertain on which applied modules to take.

I got and A* in Maths overall with As in C1-C4, A in M1 and a B in D1.

I was thinking S1 (however I haven't done statistics since GCSE), plus maybe M2 and M3 because I hated decision.

Just wondering if anyone has any relevant advice to offer?

Hey! I took S1 M2 and M3 (and M4) as well! I was in the exact same position as you since I hate decisions and changed to M3 halfway through the year.
M2 and M3 are easier than M1 questions wise but more in depth content wise, S1 is quite easy though M4 is more fun so if you're really into mechanics try that
Good luck!

Depends what you enjoy more; working with data, or working more with physics style problems.

S2 can be done quickly and the exam questions are rather predictable
