First, do I understand correctly the rules for getting A* in A-Level: a) get an A b) get 90%+ in A2 units So how does this apply to a student whose A-Level Maths units are C1-4 and two of D1,S1,M1? Does b) above only apply to C3 and C4? Or does one of the applications get counted as an A2 unit? If so can either count? Or does matter when they were taken? Thanks.
