Audrey, NEET is the entrance examination for admission to MBBS,BDS, Ayush and Veterinary courses across India. And to be eligible for NEET, you should have completed your 12th, passed in all subjects and secure a minimum aggregate of 50% in Physics, Chemistry and Biology. It is 50% for General Category, 45% for PWD and 40% for OBC,SC,ST. Now if you belong to OBC Category, the Category you belong to should be also listed in the Central OBC list. Or else you will be considered as General Category and so you have to secure a minimum aggregate of 50% in Physics, Chemistry and Biology. This 50% is inclusive of the Theory and Practical marks scored in Physics, Chemistry and Biology collectively. You needn't score 50% in Physics, 50% in Chemistry and 50% in Biology separately. You need an aggregate of 50% or 40% depending on your Category as an aggregate in Physics, Chemistry and Biology. And along with Physics, Chemistry and Biology, you should also have studied English as one of the core subjects in your 12th. This is where the importance of your Board exams in NEET end. To appear for NEET, you need to secure the minimum aggregate in your 12th. And NEET is the only entrance examination for admission to MBBS both in India and abroad as well. Now even if you have to study MBBS abroad, NEET is mandatory. So to qualify for NEET, it is important for you to score 40-50% in Physics, Chemistry and Biology in your 12th depending on your Category. But for admission to MBBS, it is your NEET score, Rank in the merit list, cut offs and your Category that matter. Your 12th marks dont count there.
