Hello aspirant,

I would like to tell you that YES, you can study class 11th and class 12th again, but you can not study from the same Board from which you have passed class 11th and 12th. You have to take admission from a different board to study again class 11th and class 12th.

You can Simply apply in that board's +2 with your class 10th marksheet. Although you can go for improvement exams from your previous board.
