CBSE Class 12 Supplementary Revaluation 2026: Critical Dates, Fees, and Rules You Must Know

CBSE will open the Class 12 Supplementary revaluation and verification window from September 7 to 9, 2026. Only candidates who already obtained the scanned answer book can apply. Applications for scanned copies closed on September 1. Fees are reduced this year, but marks can also decrease after review. Plan submissions before the window shuts at midnight.

The revaluation window runs online only, and one application is allowed for each facility. CBSE states its post‑result portals remain open until 11:59 pm during notified windows, so avoid last‑minute rush on September 9. The scanned‑copy step for this cycle ran from August 31 to September 1.

CBSE Class 12 Supplementary revaluation window: fees and what each option means

Use “Verification of issues” to flag missing pages, blurred scans, or wrong posting of marks in the supplied copy. It costs Rs 100 per answer book. Use “Re‑evaluation” to challenge marking of theory answers at Rs 25 per question. If marks increase, CBSE refunds the fee; duplicate or excess payments are also refunded.

CBSE Class 12 Supplementary revaluation window: eligibility and documents checklist

Eligibility is gated. Only candidates who applied for, and received, the scanned answer book can proceed. Keep these ready: Aadhaar linked to a working mobile number, admit card details, roll number, payment method, and the scanned‑copy PDF for reference. Submit only through the online portal; one application per facility is permitted.

CBSE Class 12 Supplementary revaluation window: result timeline, risks and helplines

Outcomes may increase, decrease, or remain unchanged; even a one‑mark reduction will apply, and the decision is final. Revised results and marksheets are uploaded to DigiLocker in phases. For support, use CBSE’s 24x7 counseling helpline 1800‑11‑8004 or central helplines listed on CBSE’s contact page. Apply only via cbse.gov.in.

Students should decide quickly, review their scanned scripts carefully, and complete payment well before 11:59 pm on September 9, 2026. Keep acknowledgment receipts and monitor DigiLocker for updates. If marks rise, expect fee refunds to the source account. When in doubt, contact your regional office or the CBSE helpline promptly.
