C1, C2 and M1 will be AS maths. C3, C4 and M2 will be A2 maths. FP1 will be AS further maths. FP2, FP3, M3-5 will be arranged to maximise your grade in further maths. (So, if you get 90 in FP2, M4 and M5 then they'll go towards your further A2 and FP3 and M3 with go towards your further AS.)
Most people's modules can be shuffled around to maximise their grades but because you're doing M1-5, they have to go in order.
thank you for help but i am confused sry dont know much about the course can you tell me what should i do for as? a2?
Basically... you don't get a choice.
If you're doing A-Level maths and A-Level further maths, you'll use all of the modules you listed. If you're just doing A-Level maths, you'll use C1-4 and M1-2.
