sir during registration of jee mains 2021 I unfortunately submit invalid ews certificate. now I have new ews certificate can i change it in march session correction form???

Dear student,
Yes you can correct yout ews certificate when the correction window opens for march session. Make sure that the certificate is of the same format as mentioned in the guidelines of nta. The correction window will open when the registration process for march session will be completed which us expected to start in last week of February, so the correction window could open in second week of March.
