Can a Maths A level Consist of M1 and M3??

So i've just got my results back and i did a Further Maths AS as well and this is what i have

C1 -99
C2 - 85
C3- 88
C4 - 71 (retaking)
M1 - 95
S1 - 87

Further Maths AS
FP1 - 77
M2 - 77
M3 - 0 (retaking)

For Maths I have an A, and for Further Maths I have a C, I was wondering if i could have S1 and M2 as part of my FM, and have M1 and M3 as part of Maths, that way i'd only need 42 in M3. I'm quite confused please help
