NUS Semester 2 Results AY 2011/2012

Hey...so its my 2nd semester, first year in NUS. when i got my sem 1 results, i was quite happy because i got all Bs. i thought it was good because back then in JC, its hard for me to even pass a subject. however, when i compared my CAP with the rest, i realised that its not so good afterall. now, in sem 2, i improved quite a bit. my cap increases from 3.6 to 3.75. im hoping to increase it to 4 eventually. now im having a headache thinking of what course i should major in.. hahaha...is it very difficult to move your CAP? 

Btw, here's my results: I dont know whether I should be happy or sad.

MS 2211: A-

MS2212:B+

SE1101E:B-

LAC1201:B+

EL2201:B+
