Hello Aspirant,

You can re-appear for class 12th board examinations but note that your eligibility will be counted from your very first appearance in class 12th examinations. So if you appear for class 12th examinations in 2022 i.e. in this year then you will be eligible for JEE-Advance 2022 and 2023 provided that you qualify JEE-Main for those years. ow if you take a drop and want to appear for JEE-Advance 2023 then you can do so but note that, JEE-Advance 2023 will be your last attempt.

At this point of time it is not certain whether the 75% criteria will be restored or not but if it gets restored then you might not be able to appear for JEE-Advance exam even after qualifying JEE-Main because to appear in JEE-Main there is no percentage limitation. But there are many students who have scored less than 75% as the relaxation was given for this year and last year, so in common interest, the authorities might announce some provision for them so that one who has secured less than 75% in this pandemic can also appear for JEE-Advance and can also take admission to NITs/IIITs/CFTIs on the basis of their JEE-Main score.

But as of now there is no any news of getting it restored for JEE-Main 2022 or JEE-Advance 2022 even by JEE-Apex board, so you have to wait for it.

I hope this information helps you.

Good Luck!!
