Chandana, you need to study Physics, Chemistry and Biology in your 12th to be able to study MBBS in India. NEET is the entrance examination for admission to MBBS colleges across India. Now if you are a MPC student, you wouldnt have had Biology as a subject. In that case, you can study Biology as an additional subject from NIOS and then appear for NEET. The only catch is that you should have secured a minimum aggregate of 50% in these 3 subjects if you belong to General Category. It is 45% for PWD and 40% for OBC,SC,ST. There is no upper age limit for NEET now. So you can try this way.
