Hello Aspirant,

Don't worry age is not an issue for JEE-Main and JEE-Advance but you can check that for NITs/IIITs/IITs because institutions have certain age limits.

Yes definitely you can appear for JEE-Main and upon qualifying it you can appear for JEE-Advance 2023 if you will be completing your last semester by that time and also note that before JEE-Advance 2023 your course must get completed because on the basis of your score in qualifying examination your eligibility for JEE-Advance will be decided.

Also note that academic gap does not matter in JEE-Main and JEE-Advance.

Note that maximum attempts allowed for JEE-Advance is 2 in 2 consecutive years, first attempt in the passing year of class 12th or equivalent examination and second attempt in very next year to that. Similarly for JEE-Main maximum attempts allowed for JEE-Main is 3 in 3 consecutive years, first attempt in the passing year of class 12th or equivalent examination and second attempt in very next year to that followed by third attempt in third year.
