It’s pretty much same as the CBSE regular one.
- You have to fill a form in the month of september – October
- Then you would have to download admit card in the month of February from http://CBSE.nic.in
- Then you would give exams like other regular students give according to their datesheet in month of March – April.
- Then CBSE check your sheets in pretty much same way like regular ones.
- Then CBSE declares your results with other students in the month of May – June on cbseresults.nic.in
Everything happens in a pre defined manner by CBSE.
