Dear Hritika, for being eligible for NEET, you should be 17 years atleast by December 31st of the year of admission. For example, if you are appearing for NEET 2020, you should be 17 years by December 31st of 2020. Now in your case, you will be 16 years and 11 months. You are short of 17 years by 20 days. So unfortunately you are not eligible for NEET. You may have to wait until next year.
