Hello Mec Lone,

The correction window for Jee Mains April session is to be started today itself. The image correction has already started and you can modify/change your image (photograph/signature) if you are facing any problem with it by going onto their official website (link below).

The correction facility for the application form will be started anytime soon today and will be applicable till 15th March.

Hope this helps. For more queries comment down below.

Good luck!
