Yes, it is possible to repeat the 12th grade at a different school, but the process may vary depending on the school and educational board. It is recommended to contact the school you are interested in attending and ask about their specific admission requirements for retaking the Class 12th.

Hello

Yes ,you can repeat class 12th even after passing it because of some reason . You can repeat it if there is not more than 2 or 3 years of gap between 10 th and 12th . If there is more gap then you need to give 10th exam also and then 12th exam .

Hope this helps

Regards
