Abhishek, Psychiatry is a Specialisation after MBBS. NEET is the entrance examination for admission to MBBS,BDS, Ayush and Veterinary courses across India. So 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. Once you appear for NEET and secure a seat in MBBS, you study MBBS for 50 months and then after 1 year of mandatory rotational internship, you are a qualified MBBS Professional. Post this, you have to appear for NEXT which will be the mode of admission to MD in Psychiatry after MBBS. Right now it is NEET PG but it will be replaced by NEXT.
