Hey.

As per the latest Supreme Court judgement, upper age limit has been waived off. For 2020, NTA has not yet given any age limit. But The lower age limit to be eligible to take NEET 2020 is a minimum of 17 years as on the date of admissions or by December 31, 2020. Youll be eligible only if you complete 17 years by 31 December 2020. You don't seem to be eligible as you won't be 17. You can use the link below for updates.
