CBSE has a three tier system to address the grievances of candidates after declaration of results (Main Exam. as well as Compartment Exam.). The candidate can apply online for the full process as per the schedule alongwith processing charges:-
1. Verification of Marks
2. Obtaining photocopy of Answer Books
All the three processes are interlinked meaning thereby a candidate who applies to process 01 can go for process 02 and thereafter for process 03. Schedules are released by the CBSE on its website after the declaration of Class XII and X results respectively.
