Hello,

Let's take an example. If a student gave their boards of class 12th in 2021 and also qualifies to jee advanced in 2021 then he/she can give the jee advanced in the next year if they want to improve their score or marks so this person is eligible to sit for jee advanced in 2022.

At the same time if another student gave their boards in 2021, cleared the cutoff of JEE main but didn't sit for to give JEE advanced and directly he sit for jee advanced 2022 and didn't score well.

If this person wants to sit for JEE advanced in 2023 then he isn't eligible.

JEE advanced releases the eligibility criteria every year but these are the main rules.

Note:- students of batch 2020 are given relaxation, they can appear in JEE Advanced 2022.
