Hi

Jee mains eligibility criteria says a student can give JEE mains for 3 consecutive years from the time of passing his/ her 12th standard exam and also a person appearing for 12th standard can also apply. A person passing in 2020 will be eligible for JEE mains 2020, 2021, 2022. The person should have the following subjects in his  12th standard which are:

B.E/ b.tech- physics, Mathematics, any one( chemistry, biology, Biotechnology  etc)

B. Arch- maths, Physics, chemistry

B. Plan- Mathematics

There is no age limit in jee mains, and you can give all the 4 attempts for the given 3 consecutive years. Yes, you are eligible for jee mains 2022 if you passed your 12th standard in 2020, but this will be your last attempt, best of luck.
