Hello,

Firstly you can appear for CBSE board three times only.

So if you getting failed again and again there are plenty of other things for you.

Firstly you can take admission in NIOS board and do open schooling.

Second option you can do a diploma courses.

There are many options for in this you can do Computer Science related Diploma, medical diploma etc.

If you have failed in any subject you can reappear for that exam again.

Hopefully this helps!!
