This year, nearly 1.63 lakh students have been placed in the compartment category following the CBSE Class 12 Board Examinations 2026, which were conducted from February 17 to April 10, 2026. Candidates are advised to reach their examination centres well before the reporting time and strictly follow all instructions issued by the Board.

Candidates should carefully verify the timing mentioned on their admit card, as reporting time may vary depending on the subject.
Students appearing for the supplementary examination should carry their CBSE Supplementary Admit Card 2026 along with a valid school identity card or government-issued photo ID, if required.
Candidates should report to the examination centre at least 30 to 45 minutes before the commencement of the examination to complete entry formalities. Late entry may not be permitted once the examination begins.
Students must carefully read all instructions printed on the question paper and answer booklet before attempting the examination. They should use only the permitted stationery items and avoid carrying prohibited materials such as mobile phones, smart watches, calculators (unless specifically permitted), Bluetooth devices, written notes, or any electronic gadgets into the examination hall.
Candidates are advised to maintain discipline inside the examination centre and strictly follow the instructions of the invigilators. Any use of unfair means may result in cancellation of the examination.
The CBSE Class 12 Supplementary Examination offers students a valuable second opportunity to improve their academic record and qualify for higher education admissions. Students should revise important concepts, reach the examination centre on time, and remain calm while writing the examination. Following all examination guidelines and managing time effectively during the paper will help candidates perform to the best of their ability and successfully clear the supplementary examination.
