Hello Buddy! Hope you are doing good.

As you passed your class 12 in 2020 then you will not be eligible for JEE Advanced 2022 or 2023. For JEE Advanced eligibility criteria, the candidate is either appearing or passed last year their class 12 boards. Other eligibility for JEE Advanced is you must have to qualify JEE Mains cutoff and be in first 2,50,000 students. So if you are not giving JEE 2020 or 2021 then you are not eligible for further appearing for JEE Advanced but if you again want to give your class 12 boards then with that you can be appear for JEE. As you say you will give class 12 boards again in 2022 then you will be eligible for JEE Advance in 2022 and 2023 respectively (when JEE Mains cutoff clear). So study well, do your preparation for JEE and your boards too as in JEE you will be eligible for JEE Advance only when you qualify the cutoff. Hope this will help you.

ALL THE BEST! WORK HARD !!
