Hello Subhadip,

There is no longer any limit on attempts in NEET. Candidates should just ensure they fulfill the upper age limit criteria.

Age criteria for NEET is as follows-

NEET will have an upper age limit of 25 years for candidates belonging to Unreserved  categories and of 30 years for candidates belonging to reserved category.

To make it clearer, you can refer to the dates produced by CBSE-

For Unreserved Categories- Candidates should be born on or between May 7, 1993 and January 1, 2002

For Reserved (including PH/PwD)- Candidates should be born on or between May 7, 1988 and January 1, 2002
