AM I eligible for JEE 2023 or IIT I have scored 71% in my boards

Hello Aspirant,

See this year you only need to pass class 12th, there is no need to be in top 20 percentile or should have at least 75% in 12th, therefore you can apply for it in this year as well but if you want to appear for 2023 then there might be problem for you if the criteria gets restored because then you will become ineligible for JEE-Advance 2023 even after qualifying JEE-Main 2023 because to appear in JEE-Main no minimum percentage is required but for JEE-Advance you need to qualify JEE-Main as well as you must have 75% in class 12th if you belongs to General category, in the case if criteria gets restored otherwise you can appear for it in 2023 as well.

Also note that you can appear for JEE-Main 2023 even if you have not scored 75% marks in class 12th this is because there is never a requirement of any minimum percentage in class 12th for JEE-Main but the 75%  is required for admission to NITs/IIIT/GFTIs on the basis of your JEE-Main score or to appear for JEE-Advance.

But you can get admission in other colleges to by only appearing in JEE-Main depending upon the eligibility criteria.

Also 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.
