Hello,

The eligibility requirement for NATA is that a candidate must have passed 10+2 with Mathematics, Physics and Chemistry with 50% aggregate taken together in the subjects mentioned and must have passed with 50% overall aggregate. Now you have not mentioned your board and maximum marks if each subject is for 100 marks then your aggregate percentage in PCM is 42.6% and this makes you ineligible to to appear in NATA. You may have you either appear in improvement exam or seek admission in any other course.
