Dear Supriya, as of now there is no upper age limit for appearing for NEET. The minimum age is that you should be 17 years atleast by December 31st of the year of admission. Taking that into consideration, you are eligible for NEET. You should also have completed your 10+2 with a minimum aggregate of 50% in Physics, Chemistry, Biology/Biotechnology as your core subjects. It is 50% for General Category amd 45% for SC/ST/OBC and 40% for PWD.
