Hello aspirant,

A student can certainly retake the class 12th board exam.

However, there is no provision for offering an exam on a single subject. To be eligible for the exam, you must take all of the subjects from class 12th.

The National Institute of Open Schooling (NIOS) is a government-sponsored programme that assists students in passing the class 12th exam and increasing their percentage in the event of a change in board.

But in my opinion you should not give the improvement exam. I would rather suggest you that you should try to get admission in good college.

Thank you

Hope this information helps you.
