You can log in to the portal using the registration/admission number and the password allotted by the Office of the Controller of Examinations. If you do not have an allotted registration number, you can log in using your admission number and date of birth (in the format yyyy-mm-dd).

Log in to the portal and select 'OD Application', then click the 'New' button to apply for OD. In the application, enter the required number of days and hours for which you are applying for OD, and then save the application.

No, you cannot edit your application once it is saved or submitted. However, you can delete the application if its status is 'Pending'.

OD will be reflected in your attendance data only after the application is approved by the concerned authority.
