CBSE admits 2 Class XII students marked on wrong answer sheets, to revise marks
The controversy erupted after Class 12 student Vedant Srivastava alleged that the Physics answer sheet uploaded by CBSE under its new Online Script Monitoring system did not belong to him, raising fears of serious evaluation errors that could impact marks and college admissions.

The Central Board of Secondary Education (CBSE) has admitted to discrepancies in the evaluation of Class 12 answer sheets and said marks will be revised in two cases after a student’s viral social media post exposed an apparent Physics answer sheet mix-up during the re-evaluation process.
The controversy erupted after Class 12 student Vedant Srivastava alleged that the Physics answer sheet uploaded by CBSE under its new Online Script Monitoring (OSM) system did not belong to him, triggering concerns over serious evaluation lapses that could affect marks and college admissions.
On May 23, Vedant shared a series of posts on X, saying he was left “shattered” after receiving photocopies of his evaluated answer sheets and discovering that the Physics script shared by CBSE appeared to belong to another student.
Following the uproar online, CBSE acknowledged the mismatch in the Physics paper and also accepted a separate complaint linked to a Chemistry answer sheet, prompting fresh scrutiny of the board’s digital evaluation and verification mechanisms.
The Board’s Joint Secretary (Coordination) also wrote to Vedant, attaching what was described as his correct Physics answer book and confirming that his result would be revised accordingly.
VEDANT'S CORRECTED COPY TRIGGERS NEW QUESTIONS
In a post late Monday night, Vedant thanked CBSE for responding to his complaint and shared screenshots of what he said were the correct answer sheets. However, he maintained that discrepancies in evaluation still persisted and said he would seek re-evaluation after examining the sheets more closely.
“Attaching the correct answer sheet screenshots here for your reference, we will still apply for reevaluation of this answer sheet after checking this sheet more closely, since they have slashed my marks even when the answer is correct,” he wrote.
The development has added a fresh layer to the controversy. While CBSE’s response appeared to acknowledge that the wrong Physics answer sheet had initially been uploaded or mapped to Vedant’s account, the student now alleges that even the corrected copy reflects questionable marking.
The reactions to Vedant’s posts on X have also opened up another line of scrutiny around CBSE’s much-publicised On-Screen Marking (OSM) system. Several users claimed the answer sheet screenshots shared online appeared to contain manual markings and handwritten evaluation indicators rather than purely digital annotations typically associated with OSM-based assessment.
This has led to wider speculation online over whether all answer scripts were actually evaluated entirely through the OSM process, or whether hybrid/manual checking methods may also have been used in some cases.
While there is no official confirmation from CBSE on this aspect, the debate has intensified confusion around how exactly the board’s new evaluation architecture functioned this year.
For critics, the issue is becoming larger than a single mismatched answer sheet. They argue the controversy now raises multiple questions simultaneously: whether scripts were incorrectly mapped, whether evaluations were consistently digitised under OSM, and whether adequate audit mechanisms existed to detect such errors before students accessed their copies.
THE CHEMISTRY PAPER CONFUSION
Meanwhile, a second case involving a Chemistry answer sheet also surfaced on social media. In a post shared online, another student said CBSE had responded to their complaint and accepted concerns raised regarding the evaluation process.
“CBSE replied to our email and confirmed that our concern regarding the Chemistry answer sheet was valid. Thank you to everyone who helped bring attention to this. Your support meant a lot. Waiting for the next steps from CBSE now,” the post read.
Sources had earlier told India Today that CBSE took up Vedant’s case on “top priority” after the issue gained traction online. The board also contacted the student directly following the widespread attention on social media.
However, alongside support, Vedant also faced online abuse after his posts went viral, with some users branding him “Pakistani” on social media.
Separately, another social media user questioned whether Vedant’s answer sheet had initially been evaluated through the OSM system at all, contrary to the student’s claim. The user alleged on X that the sheet appeared to have been manually checked only after the complaint went viral online.
According to the post, this raised the possibility that Vedant’s digitally evaluated answer sheet may have been wrongly assigned to another student.
The developments have now placed renewed focus on CBSE’s post-result procedures, including answer sheet access, verification requests and re-evaluation systems available to students after results are declared.
