I just got my AS results today.. and I'm really disappointed ...i got 2 B's and 1 C ...b in chemistry and biology..and C in physics..I expected an A in biology..now what should i do?...i might give a retake for chemistry so that i get an A...and so its easier for me to maintain dis A in alvls...as far for the biology is it possible for me to improve from B to A or an A* in a2 without giving a retake for AS?
