If you are talking about NEET, then you are not eligible. You have to score a minimum aggregate of 50% in Physics, Chemistry and Biology in your 12th. English marks are not considered in NEET. So, if your aggregate is only 49.3%, you are not eligible for NEET because they will not count 49.3% as 50%. You better write improvement exams.
