I have grace marks in 12th physics,,in pcb aggregate 53%without counting grace marks ,am I eligible for neet ug

There are certain criteria to be eligible for Neet. As per the Neet eligibility criteria, the candidate must has passed 12th or equivalent from a recognized board with English and Physics, Chemistry annd Biology or Biotechnology (have to pass in both the theory and practical examination) with at least 50% (for general category) marks in aggregate of PCB (Includes both theory and practical score) and this is 40% for OBC, SC and ST candidates and 45% marks for PwD candidates. It doesn't matter if you have passed with grace Marks in 12th. So if your total PCB percentage is greater than 40 (as you belong to OBC category according to your last query) and if you have passed all these subjects in both theory and Practical, then you are eligible for Neet 2021. Now without counting grace marks you already have 53%. So you are eligible. http://medicine.careers360.com/articles/neet-eligibility-criteria
