I know that its not easy to digest this kind of result, specially when u r to close to 200.
but try to think this way that ur passing is not stop or end. it just delay for 6 months, THAT'S IT.
u got very good marks in Accounts/Law & Tax. lacking is in costing only &its for 10 to 12 marks only .
U have now 100 to 105 days & now only 1 subject (costing only) more to prepare. SO JUST GO FOR ITTTTTTT.
BANG IT IN MAY 12, & BE CONFIDENT . IMP is what u think 4 urself .
