Hello,

For class 12 Boards, there are no specific mock tests.

Rather sample papers are available, both from CBSE and third party vendors/sites.

These sample papers are made according to the latest blue print of the exam as released by CBSE. You can set a timer and try to practice these papers.

Sample papers for Class 12 are available on Careers360 platform in the following link:

CBSE official website:

Hope this helps.

Thanks.
