Bhoomi, the eligibility criteria for NEET is that you should have completed your 12th atleast by the time of counselling and admission. He/she should have completed his/her 12th with a minimum aggregate of 50% in Physics, Chemistry and Biology. It if 50% for General Category, 45% for PWD and 40% for OBC,SC,ST. Now lets say you write your exams in July, the result might come in August. But by then the counselling would have been complete and classes would have started. And technically you wouldn't have completed your 12th. In such case, you will not be eligible for NEET.
