Chinese O lvl results..

I don't know if I should be happy..or sad...
when i heard my results I din know what to do..
I got a b4..
so I was thinking..weather I should retake my paper or not..anyway..in my previous tests and exams I would always get a c5-6 now i got a b4..i improved...I seem to be satisfied..but then again..I feel like giving it another try. waht should I do? *ponders*actually, I told myself not to re take the paper..Ms Low gave some kind of 'inspiring' adivce for the whole 2 periods of history..and told us that if we had done our best..we should forget about it. A b4 already warrants me to go JC...But Mr Tan says I can do better...and here Ms low is giving advice not to "waste your bullets on one warfront alone" then bla bla bla..hmmmm..I feel quite confused..But it's true you know..I know I cannot get an "a" for my chinese paper.. so at most I can jump a grade higher to B3..If I would want to retake..i have to attend more lessons..and practice more..time can be spent to improve on other subjects..
wat shld I do?
hmmmmmm.....
