hi sreekesh ,

thank you for aproaching us . if you have been alloted a particular date for counselling , you will have to report on that day itself . but  ,if there are some kind of unavoidable conditions due to which you will not be able to attend on the specified date , contact the counselling cell or the helpline for counselling for the enterance examination you have written and convey them your condition . they will surely consider and help you out .

all the best
