Hello aspirant,

i hope that you are doing absolutely great.

With reference to yoru above mentioned query, i would like to tell you that Yes, the 2020 JEE aspirants were allowed to give their attempt in the year 2022 year, due to the pandemic situation, but now since the pandemic is getting in control and we are recovering from this global crisis, I don't think that the JEE 2021 aspirants would be allowed to give an extra attempt again in JEE 2023 year.

So, I think that you must leave all you hope on this situation, because the situation is improving continuously.

This was just my perspectives.

I hope that this will help.
