For weeks, 17-year-old Kushal Jain believed he had underperformed in Chemistry. The student from Dwarka in Delhi had scored 97 in Physics and 97 in Mathematics in the CBSE Class XII Board examinations. But his Chemistry score was 79 — a result he found difficult to accept considering his performance through the year.
“I had expected above 95,” he said. “When the results were declared, I assumed there had been a mistake.”
When the outcome of CBSE’s post-result verification process arrived this week, it revealed just how large that mistake may have been.
Kushal’s Chemistry marks had jumped from 79 to 100.
The revision transformed his Physics-Chemistry-Mathematics (PCM) aggregate from 91% to 98%, a seven-percentage-point increase that he described as “massive”. “The 7% margin is very massive,” he told The Indian Express.
Glitches left students in limbo
His case is one of several that have emerged from CBSE’s first year of On-Screen Marking (OSM), a digital evaluation system introduced across Class 12 board examinations with the promise of reducing human error and improving efficiency.
Instead, several issues were flagged. Many students questioned discrepancies they observed after obtaining scanned copies of answer books. Some even wondered whether the scripts uploaded to them belonged to them. Principals, evaluators and senior teachers who spoke to The Indian Express had alleged that the rollout was rushed, inadequately tested and difficult for many evaluators to navigate.
Kushal said after the Class 12 results were declared on May 13, he tried accessing his evaluated answer book through CBSE’s portal. But the platform malfunctioned, he said, while deadlines for obtaining answer scripts and applying for re-evaluation were repeatedly extended.
On May 29, CBSE announced that its Post-Result Activities portal would become operational only from June 1, saying additional time was needed to ensure a “transparent and glitch-free process” and maintain the “highest standards and protocols of evaluation”.
Students worried that the delays were colliding with college admission timelines.
“The registration for Joint Admission Counselling (JAC) Delhi was to close on June 9. My counselling was supposed to start on June 2. CBSE kept extending the dates and students were stuck in limbo,” Kushal had said at the time
The revised marks ultimately did not affect his immediate admission prospects, as he is pursuing engineering admissions through JEE Main rankings and hopes to secure a seat in a government institution in Delhi.
But he said the change underscored how significantly an evaluation error could alter a student’s academic record.
“If I wanted admission in a private university, my PCM aggregate would matter a lot,” he said. “For higher studies later, whether MTech or MBA, these marks could matter.”
Record re-evaluation rush
This year saw an unprecedented volume of post-result requests. More than 4 lakh students applied for over 11 lakh scanned copies of answer books after results were declared. Over 1.60 lakh students subsequently sought verification of marks or re-evaluation covering more than 3.80 lakh answer books.
On Sunday, CBSE announced the outcomes of post-result services for nearly 1.47 lakh students, about 87% of the approximately 1.68 lakh candidates who had applied for verification and re-evaluation. Revised marksheets are being issued through DigiLocker, while remaining cases will be processed in phases.
Students whose applications show “no change” will be allowed to inspect their answer books at regional offices, with schedules to be announced separately.
The CBSE has maintained that the process was conducted under the supervision of technical experts from the Digital India Corporation, IIT Kanpur and IIT Madras to safeguard the integrity of the system and prevent unauthorised access.
Among classmates and fellow applicants of Kushal, he said, most revisions he has heard about involved three to five additional marks.
“As far as I know, most students saw an increase of three or five marks,” he said. “Only I had such a huge gap.”
