Hi, I'm currently doing A2 further maths and taking Fp2, Fp3 and M2 this year. From what I've read you need 270 UMS from your top 3 A2 modules. As I've got 89 in D2 I only require 2 more modules but I was thinking if I took S2 as an extra precaution and got 91+ in that module and 90 in Fp2 but lower than 90 in both Fp3 and M2 would S2 possible replace the lowest of the 2 modules? Or would S2 have no effect on my Further maths and remain an extra separate module?
