Hi

No dates for application correction or image correction have been mentioned.

However, students will be able to correct mistakes in limited items only. No changes will be allowed in the fields of test centre and courses. Once it is selected during the time of application, it will not be changed. 

Correction in uploaded images will be done through online and correction in other details will be made via offline mode.

Candidates who have defects in photograph/signature/thumb impression uploaded in the application their admit card will not be generated unless they correct their defects in the given time frame.

So you will have to wait 

Regards
