hello dr shagun gautam

I hope you are doing good. As per your query , I would glad to tell you that for appearing in neet exam candidate should be atleast of 17 years . Generallly students  passed their 10th in 16 year of age . The upper age limit of neet exam is 25 which means candidate above 25 are not eligible to appear for exam . So if we consider that you weren of 16 in 2015 and you will turn 21 into 2022. In that case you are eligible to give exam

Hope you found this answer helpful. Good luck for your future
