11 registration number kaisa check kra

Hello Sandeep, 

CBSE registration involves two steps, first, the school registers itself on the CBSE portal. Next, they submit all the details of their students on the same portal via login through the user id and password provided by CBSE for that student. Every student is given a unique registration number. This happens in IX and XI. You can find your registration number on the top right corner of the X marksheet. 

All the Best!
