Dear Mriganka,  candidates can make corrections to their application form tentatively from November 21 till 30. Candidates whose applications are found with mistakes or discrepancies will be intimated about the same within 15 days from the closure of the registration. Thereafter they will be given a week to  rectify the same.

 I would also suggest you to reach out to them at mail@natboard.edu or call them at their helpline +91-11-45930000 Monday to Friday from 9.30am to 5.30pm
