Dear Pulkit, though you have failed in your 12th last year but managed to complete it later passing in all the subjects and score a minimum aggregate of 50% in Physics, Chemistry and Biology, you are eligible for NEET. It is 50% if you belong to General Category, 45% for PWD and 40% for OBC,SC,ST. There is no upper age limit for NEET and also there is no cap on no.of times you can appear for NEET.
