You haven't mentioned in which course you want to take admission. There are many courses (such as BSc, BA) available. The basic eligibility criteria is that the candidate must have passed Higher Secondary/Intermediate (10+2) from a recognized board. It is difficult to predict the actual marks for admission as it depends on various factors such as number of candidates, highest marks obtained in the qualifying exam, number or seats also. But you should give your best and should aim to score at least 80% marks in your higher secondary so that you can get into your desired branch.
