Hello aspirant.

You can edit the application as long as it is open that is till January 16, 2021, and download the revamped application form. Also as per NTA guidelines, the applications will be released for every session individually, hence you can also apply then. Thereby you can edit your application form till the application is open and if you fail to edit when the application form is open. Then the NTA will release the editing application dates and you can edit then. As per NTA new announcement, corrections of the application form for the February session begin from January 19 to January 21, 2021.

Hi.

YES you are allowed to edit the session you have opted as long as the application window for JEE Mains registration is open.

Good Luck
