Hi !

The upper age limit has been removed completely by the Supreme court as if now , there may be changes in the criteria , but it is valid for both regular and open students appearing for class 12 boards. Any candidate with any age belonging to any school (regular or open) is eligible to give the exam.

Hope it helps !
