what is the minimum number of questions need to be done to get good percentile in cat exams?

Hi Santosh, All the good Institutes will look into overall as well as sectional cut off, although it would not be possible to give any exact number of Questions one should attempt to get a good score but yes, you need not attempt the whole paper but on the basis of your judgment pick up those scori

you could not measure it., it depends on the total number of candidates cleared the exam.. just do your best and answer only correct.
