Question about getting an A* in Mathematics

[imanmalik]

I don't know my component grades but I got an A in the M/J 12 (AS) (P12+42). Let's consider the worst situation...I got a borderline A or low A. Grade thresholds for an A were 58/75 (p1) 31/50 9(p4). So you need 89/125 to get an A. Let's say I got 93/125. Is it possible for me to bring my grade up to an A* by getting marks in P3 and S1? Or is it better if I redo P1 and M1?
(I didn't study for my AS sooooooo yeah xD)

Should be possible. difficulty depends on thresholds so I cannot say by how far.
