Hey Rajashekar,

Jee Mains 2021 correction window to edit the application form has been closed in January 2021. Even the admit cards are released for February session of 2021. But do not worry, the application form and correction form for JEE MAINS 2021 March session will also open in the month of March 2021 or February end (most probably). So, you must submit your valid EWS caste certificate at that time.

Thankyou.
