CBSE verification and re-evaluation portal timeline and eligibility
The online portal for verification and re-evaluation went live on June 2, CBSE said. The board said it opened the portal on Tuesday for Class 12 students who were unhappy with evaluation. CBSE added that only students who already received scanned copies of evaluated answer books could use the facility.
CBSE said the portal would remain open till June 6 midnight. It said no offline requests would be accepted, and late submissions would be rejected. Students must log in on the CBSE website using an Aadhaar number. CBSE said Aadhaar-based checks were added for security, with alternatives for students without Aadhaar.
For students without Aadhaar, CBSE said Aadhaar details of parents, relatives or guardians could be used. The board said the Aadhaar name, date of birth and gender must match the person whose number is used. CBSE also said students should apply within the fixed timeline, and results would be shared after processing ends.
CBSE verification and re-evaluation portal fees and rules
CBSE said verification of issues in scanned copies cost Rs 100 per answer book. It added that re-evaluation would cost Rs 25 per question. Students can raise issues like missing pages or sheets, blurred pages, wrong answer books, missing maps, or marking against a different question paper set.
CBSE said students should include all subject requests before final submission. It said students may file only one application each for verification of issues and re-evaluation. CBSE added that once \"freeze and proceed to payment\" is selected, entries get locked and cannot be changed.
CBSE said an application counts as submitted only after payment succeeds online. It added that students may seek re-evaluation for one or more questions across subjects. Applicants must give details such as question number and page number when needed. CBSE said a visual guide and tutorial video were shared for support.
CBSE verification and re-evaluation portal cyberattack and access concerns
The portal launch came after a delay, as CBSE earlier expected applications to begin by May 29. The process also followed concerns about the on-screen marking OSM system for Class 12 exams. Students and parents reported glitches, payment failures and access problems during verification and re-evaluation.
CBSE earlier said malicious actors tried to disrupt services with cyberattacks. The board said a denial-of-service attack caused 1.5 million hits within two minutes. It also reported more than one lakh attempts at unauthorised file access. CBSE said it introduced longer session limits after student feedback.
On Wednesday, CBSE said it again blocked a denial-of-service attempt and continued system monitoring. It said improvements were being added to make the portal faster and smoother for students. With applications and payments running through June 6 midnight, CBSE reiterated that students should use official CBSE communications for updates.
