Hello aspirant,

Yes, you can surely repeat 12th class with same subjects in CBSE board if you get compartment or for a few subjects. You can repeat it if there are not more than 2 or 3 years. If you have passed but with a low percentage then you can give improvement exams as a private student in the subjects you want to improve.

But if you totally repeat 12th class with all subjects when you already passed lastly without any compartment then you need to face some difficulties. you can look for other Boards or other schools to go to.

Thank you
