The digital platform had suffered a temporary shutdown over the weekend following server crashes caused by a sudden surge in traffic. For tens of thousands of students dissatisfied with their recent Class 12 board results, the relaunch brings immense relief, though the window to apply remains highly restricted and time-sensitive.

To help students navigate the system without further technical delays, here is the official step-by-step breakdown of how the board’s multi-tiered grievance process works.

The official CBSE re-evaluation process

Students must follow these four phases strictly in order. The board has clarified that skipping a phase or missing a deadline automatically forfeits a student's right to advance to the next level of appeal.

1. Apply for verification of marks

Log onto the official CBSE website (cbse.gov.in) and select the 'Pariksha Sangam' portal. Fill out the application form for your chosen subjects and pay a processing fee of Rs 500 per subject, or Rs 100 per question for reevaluation. During this phase, officials will strictly check for totaling errors, omitted answers, or unchecked pages.

2. Obtain a photocopy of your answer book

Only students who completed Phase 1 can apply for this step. If you remain dissatisfied with the verified total, you must request a scanned copy of your evaluated answer booklet. This application requires a fee of Rs 700 per answer book and provides the transparency needed for the final challenge.

3. Identify specific marking scheme errors

Once you receive your scanned booklet, compare your answers directly against the official CBSE marking scheme answers uploaded on the website. You cannot challenge the whole paper arbitrarily; you must pinpoint the exact question numbers where you believe marks were wrongfully withheld.

4. Submit final re-evaluation request

Using the portal, submit an online challenge for the disputed questions. Students must pay a non-refundable fee of Rs 100 per individual question challenged. A fresh, senior examiner will re-evaluate those specific answers, and the new score will be locked in.

Critical risks and guidelines

Board officials have urged students to watch the instructional video posted to their social media handles carefully before submitting payments, as all fees are strictly non-refundable.

Furthermore, students are reminded that this process carries inherent risks. If your score decreases during re-evaluation, the lower score becomes your official final mark. Your previous marksheet will be rendered legally void, and you will be required to surrender the physical document back to the CBSE headquarters before receiving your updated credentials.

Why the controversy erupted in the first place

The sudden disruption of the portal follows weeks of growing friction between students, parents, and the central board over the first-time implementation of the On-Screen Marking System (OSM)—a digital framework used to scan and grade nearly 98 lakh answer booklets this year.

When the initial results were released, hundreds of thousands of applicants alleged widespread discrepancies, claiming that the digital system generated blurred scanned scripts, blank pages, and entirely overlooked answer sheets.

The crisis escalated dramatically when the board's third-party payment gateway suffered a cybersecurity breach, causing a malicious glitch that displayed random, absurd fee requirements ranging from Rs1 to nearly Rs 68,000 for just 50 students.

As public outcry mounted and political figures demanded accountability, Union Education Minister Dharmendra Pradhan publicly took responsibility for the technological oversight, bringing in cybersecurity experts from IIT Madras and IIT Kanpur to fortify the digital infrastructure before authorizing Tuesday's relaunch.
