Before Covid-19 pandemic, 75% criteria in 12th Class to sit in JEE Main was mandatory.
During Covid-19, this 75% criteria in 12th Class was omitted to sit in the JEE Mains 2022 exams, as schools were closed.
There is no official declaration of 75% criteria in 12th Class to sit in the JEE Main 2023 exam, but you can expect it because there are rare cases of covid-19.
For students who got selected in JEE Main 2022 exams, this 75% criteria is not applicable for them.
There will be a different 75% criteria for JEE Mains for students who are appearing for the 12th board in 2023 and who already appeared in 2022.
