Dear aspirant

It is not necessary to provide your 11th class roll number.

If you have your 11th class marksheet, then you can provide the details like roll number, marks, etc mentioned in the 2nd phase registration.

But if you don't have 11th class roll number, then follow the steps to submit the form without entering roll number :

1. Do not select any option in the tab "Result mode". Keep it to default 'Select' option.
2. Leave the tab "Roll number" blank.
3. Fill all the other necessary details.
4. Submit the application form.

Hope this will help !
