Dear Manoj, if you have completed your 10+2 and cleared all your subjects either the first time or in supplementary exams, you are considered passed and are eligible for NEET. Now regarding securing 52%, you havent mentiones whether it was the aggregate of all subjects or just Physics, Chemistry and Biology. Now for being eligible for NEET, you should have scored 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.
