Hello Gajula,

Cutoffs depend on the number of seats available, number of applicants, difficulty level of the exam etc.This year;s results have shown that paper was good and many have performed well. The highest mark being 720, the competition is going to be very high. With 308 marks your predicted overall rank would be around 270759 - 310909. Hence it is not at all possible to get government seat and coming to private the top ones may be difficult but do not lose hope ,you may attend the counselling and wait till the last round to see your options under home state quota in any low ranked private college.If not you may have to go for management quota.

You the college predictor to know your possibilities:
