Hello aspirant,

*****You can directly give JEE Mains, by skipping JEE Mains in 2022 will cost you one attempt down out of 3 attempts in 3 consecutive years. As already you have written JEE Mains 2021 you are left with only one attempt.

Yes, you'll be eligible for JEE Mains in 2023 as you would complete your 12 th standard in 2021.

*****You will be eligible for JEE Mains in 3 consecutive years from the year you finish your 12 th standard including that year i.e you are eligible for JEE Mains in 2021, 2022 and 2023. JEE Advanced can be attempted twice in consecutive years.
