i've heard that if u get maybe 2 very high As, like maybe close to full marks or little less, and maybe a high B for 1 paper, its possible to get A*...
cuz what if someone gets 76/80 in paper 3 (science), 37/40 in paper 6 but a 36/40 in MCQ, where 37/40 is A - so will he get an A overall even tho his weighted score with all papers is like 90%..?
this way, sum1 with an overall lower percentage may get an A* just cuz all his papers were at least A, even tho another person got a higher overall percentage but maybe a high B..
