Hello Aspirant,

See as there is no age limit to appear in JEE-Main and also you had passed your class 12th 2020 so you are definitely eligible for JEE-Main this year i.e  JEE-Main 2022 so you can definitely get admission to engineering colleges on the basis of your JEE-Main score but also note that different colleges have different eligibility criteria as well so make sure to check them once before applying.

You can use JEE-Main College Predictor to predict your chances of admission in different engineering colleges of India on the basis of your JEE-Main 2021 result :-
