There was one vague question in IDT regarding derermination of rate of duty!
Also in ISCA some questions were confusing.. Somewhere i read that when questions are not clear they keep provision for checking.. Audit and ISCA always has 2 marks grace
As if papers were designed to check the speed along with the mental stability... How much attempted doesnot matter.. how properly you did that matters.... But NO COMMON MAN can have stable mind when he comes to know that he has one hour remaining and has attemped only 40-50 marks.. Patience is tested
