CBSE: The System That Marked Someone Else's Paper

"I am a CBSE Class 12 student. We applied for photocopies of my answer sheets. And I am shattered. Because the Physics answer sheet uploaded by CBSE is not mine."

That is a 17-year-old boy named Vedant. He applied for his answer sheet after getting unexpectedly low marks in Physics. What came back had his roll number on the cover — but the handwriting inside was someone else's. The answers were someone else's. The paper that decided his Physics marks belonged to a different student altogether.

And he is not alone.

A student named Sanjana got her Chemistry sheet back. The first page carried her details. The internal pages carried completely different handwriting. Another student alleged that two full pages of a Chemistry answer sheet had been replaced entirely. Student after student began flooding X and Reddit with screenshots of papers that simply do not belong to them.

This is not a glitch. This is the systemic failure of a system that was specifically built to prevent the very errors it is now producing.

What CBSE Did

In February 2026, the Central Board of Secondary Education made a big call. For the first time ever, Class 12 answer sheets would be evaluated through On-Screen Marking — OSM. Answer sheets would be scanned at designated hubs, uploaded to a digital platform, and marked by teachers on computer screens, remotely.

CBSE's own circular sold the upgrade hard. It would eliminate totalling errors. Reduce manual coordination. Deliver faster results. Bring greater transparency. The board was so confident in the new machinery that it moved to scrap post-result verification of marks for Class 12 altogether — the safety net that had, for years, let students get a second look at their own papers.

Ninety-eight lakh answer sheets were scanned and evaluated digitally. Results came out on May 13th.

Within hours, the complaints started.

What went wrong - Three Failures, Stacked

Failure one: blurred scans. Students accessing their answer sheets through the revaluation portal found that handwritten answers were physically unreadable on screen. Margins cut off. Ink faded into nothing. Entire sections illegible. And these blurred sheets had been forwarded to evaluators anyway. Teachers were being asked to grade papers they could not actually see.

Failure two: unchecked answers. Students found questions they had clearly attempted — visible right there on the scanned copy — carrying no marks at all. Not zero. No evaluation. Skipped entirely. By a system that had promised no answer would ever go unchecked.

Failure three: wrong answer sheets. Vedant's roll number, somebody else's paper. Sanjana's roll number, somebody else's Chemistry answers. Somewhere in the scanning chain, sheets got swapped — and nobody caught it. Not the scanning hub. Not the quality check. Not the evaluator. Three separate checkpoints, and the error sailed through all of them.

And then there was the portal itself. When students tried to apply for revaluation, the system buckled. Payments glitched. Fees reportedly leapt from one rupee to 69,000 rupees. Students alleged the portal may even have been hacked. The deadline had to be extended twice.

This was the part that should have been the cleanup. Instead, it became another wing of the same collapse.

The Response: Silence The Critics

Here is what should genuinely alarm every parent watching this unfold.

CBSE's first response, when students raised these complaints, was to call the allegations "factually incorrect." The board issued a statement insisting the OSM process had been carried out according to procedure, with supervision.

And then it did something remarkable. It issued a formal notice threatening teachers with legal action for sharing "misleading or factually incorrect information" about the evaluation process on social media.

Sit with the sequence for a moment. Students are holding up screenshots of answer sheets that are not theirs. Teachers — the people inside the marking process — might be able to explain exactly what went wrong. And the board's instinct was not to investigate. It was to threaten the people who might talk.

There has, to be fair, been movement since. As the screenshots kept coming and the story refused to die, CBSE began acknowledging that some of the answer-sheet mismatch complaints were valid, and started corrective action. On May 25th, it publicly responded to Vedant himself — confirming that his Physics answer book had been examined, that the correct copy had been emailed to him, and that his result would be updated. It has slashed revaluation fees. It has launched helplines.

But all of that is damage control, arriving after the fact. It is the board reacting to a fire it spent the first week insisting did not exist.

The Real Cost

Every one of those 98 lakh answer sheets belongs to a student whose college admission depends on that number. Whose JEE or NEET eligibility depends on that number. Whose family has spent years — and lakhs of rupees — preparing for this one exam.

CBSE introduced a brand-new evaluation system, for the very first time, on a live batch of students. No phased rollout. No pilot programme on a smaller, lower-stakes set of papers. Straight to 98 lakh sheets. This was not an unforeseeable risk, either — back in February, teachers' associations had openly warned that most evaluators had not been properly trained on the new platform, and had asked the board to postpone the rollout by a session. The board went ahead anyway. And the system it trusted could not even perform its single most basic task: matching the right answer sheet to the right student.

These students do not need helplines. They do not need reduced fees. They need their actual answer sheets, evaluated by teachers who can actually read them.

CBSE owes this country an independent audit of every step of the OSM scanning and evaluation chain. Not a press statement. Not a sympathetic email to whichever student's complaint happens to go viral that week. An audit.
