Hello,

You can appear for JEE Advanced for two consecutive years from the year of passing on the qualifying examination 10+2 or its equivalent. As you have passed 10+2 in the year 2020 you are eligible to appear for JEE Advanced 2020 and JEE Advanced. JEE Advanced 2020 is already concluded so you are only left with JEE Advanced 2021. The age criteria to appear for JEE Advanced 2021 is that you should have been born on or after October 1, 1996. For candidates belonging to , SC, ST and PwD category a relaxation of 5 years is applicable (born on or after October 1, 1991). Since you belong to general category and born before October 1, 1996 you are not eligible to appear for JEE Advance based on age criteria.

To get admission in to NITs/IIITs/IITs a candidate belonging to general category must score minimum 75% aggregate marks if he/she belongs to general category, if the candidate belongs to SC,ST category he/she should score minimum 65% aggregate marks in 10+2. But this year the minimum percentage requirement is relaxed due to corona pandemic. Even though the minimum marks scored in qualifying examination is relaxed you are not eligible to appear for JEE Advanced 2021.

There is no age limit to appear for JEE Main and a candidate can appear for JEE Main for 3 consecutive years. SO you can appear for JEE Main 2020, 2021 and JEE Main 2022. You are eligible to appear for JEE Main 2021 as there is no age limit and get admission in to NIT this year even though you haven't scored 75% aggregate marks as the minimum percentage requirement is relaxed.
