I come under EWS category I didn't chose EWS category earlier but result of Mains have already declared now will I be able to apply for EWS

Dear Sonal, if you haven't selected your EWS category when NTA opened the correction window twice, you cannot opt for it now. Now that the results have been declared, the further necessary options will be based on the initial Category you have chosen. Now, unfortunately, there is nothing that can be done about changing your Category to EWS though you are eligiblr.

Sonal,
As you've applied and appeared for exam already, you can't change it now. They asks for confirmation after you submit your application. Further be careful.

Regards
