i m open inter student and I secured 50%marks in all subjects but not in chemistry .can apply for neet exam

Abhi, for being eligible for NEET, you need to pass your 12th with 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. So the aggregate of these 3 subjects should be 50%. So even if you did not score 50 in Chemistry but still have an aggregate of 50%, you are eligible for NEET.
