Anurag Khanna 13th May, 2021

Hello Aspirant,

Sorry dear but you are not eligible for JEE-Advance 2021 because as you have mentioned that you had passed your class 12th in 2019 so you were only eligible for JEE-Advance 2019 and 2020 because as per the JEE-Advance eligibility criteria the candidate can only appear for maximum of two consecutive years in JEE-Advance that includes the passing year of class 12th as well and even if you have not appeared for JEE-Advance 2019 then also your year will be counted and now you are not eligble for JEE-Advance 2021 even if you qualify for it in JEE-Main 2021. But you are eligible for JEE-Main 2021 and even this is your last attempt for JEE-Main from 2022 you will not be eligible for either JEE-Main or JEE-Advance.

For complete details about the eligibility criteria of JEE-Advance kindly check out the link given below :-
