Hello student,

For JEE Main, you get three years of attempts, first in the passing year, and two more consecutive years.

Now coming back to your question, see if you have given improvement exam in 2020 and your original 12th exam was in 2019 but you were not satisfied by your result or failed then you will not get chance in 2022 JEE Main exam. But if you freshly gave 12th exam in 2020 I mean not giving improvement or with not that same old admission of 2020 then you are eligible for JEE Main 2022.

I hope this information helps you.

All the very best!!
