Shud i apply for re verification

99% of the times reverification doesn't produce ANY results and it seems more like a way for ICAI to earn money than anything else. Even the result of it would come out so late that you would have already studied for the next exam by then. So I suggest that you shouldn't waste time, money and effort on that.

The best you could do would be probably call for photocopies of your papers and see exactly where you are going wrong (dont be surprised if the marks on the photocopies are different from those in your marksheet. ICAI is famous for manipulation of marks :D)
