Dear Simran, your aggregate should be 50% collectively in Physics, Chemistry and Biology/Biotechnology. It is 50% for General Category, 45% for PWD and 40% for SC/ST/OBC. And the catch here is the aggregate is to qualify you for appearing for NEET. Admission in Medical college has got nothing to do with your Board marks. If your question is 50% in NEET score for securing a seat, then with 50% in NEET you qualify in NEET. However, qualification doesnt guarantee you a medical seat. It depends on the merit list and category.
