Dear Divyanshi, for Undergraduation courses, you should have completed your 10+2 with Physics, Chemistry and Biology/Mathematics/Agriculture/HomeScience as core subjects. So instead if Mathematics your subjects can be any one among Biology, Agriculture and Home Science along with Physics and Chemistry. You should have completed 10+2 in these combinations with a minimum aggregate of 50%. It is 40% for Reserved categories. For Undergraduation, the eligibility is 10+2. However, the underlying fact is that you complete your 10+2 after 10th. But 12th marks are taken into consideration.
