Hello Aspirant,

No you cannot appear for JEE-Main and JEE-Advance 2022 because by July-August admission process will be completed for engineering courses on the basis of JEE-Main and JEE-Advance 2022 score and for admission process you would have to produce your marksheet of class 12th which you would get most probably by November-December 2022 so you can appear for JEE-Main and JEE-Advance 2023.

To appear for JEE-Advance you need to qualify JEE-Main and for JEE-Main, eligibility criteria is mentioned below :-
