See for most of the colleges providing MBBS admission through NEET, the eligibility criteria for 10+2 board, is that the student needs to score above 50% marks in 10+2 Physics, Chemistry and Biology aggregate. If you have greater percentage than 50% in PCB then you are eligible for the admission for most of the Government colleges in India.
