Hello,

CBSE class 12 Board exams have already commenced.

If you are a regular student, then your college/school will provide you the admit card. All the details like Admit Card Number, Center, Center Code, School Code, Subject Code, Subject Name etc. can be found on that. This hall ticket is not available online.

But, if you are giving improvement exam, then you can get them online from the official site.

Link to official site:

Hope this helps.

Thanks.
