Hi aspirant,

In general candidates are eligible for JEE advanced examination in two consecutive year starting from the year in which he or she appeared for the board examination so by following that you would not be eligible for JEE advanced examination. But according to the latest release by the national testing agency if the result is declared for the academic year 2019-20 on or after October 15, 2020, then the candidates of that board who appeared for their 12th standard qualifying exam in 2020 will also be termed eligible for JEE Advanced 2022. So even if we follow this as your result came in June 2021 you would not be eligible for JEE advanced 2023.

Hope it helps!
