CBSE adds QR codes on question papers to track papers and improve exam security.
During the Class 12 Maths exam, some students said scanning the code led to the Never Gonna Give You Up video.
CBSE said the exam was not affected and promised to look into the issue.
Have you ever wondered why CBSE puts out QR codes on the question papers you receive during your board exams? No, they are not just there to take up blank space, but they actually have a real use case. The QR code on the question paper helps the CBSE to safeguard the national examinations. However, there was a bizarre incident that took place during this year’s Class 12 mathematics exams. Several users reported that when the QR code on their question paper was scanned, it led them to the music video for Rick Astley’s ‘Never gonna give you up’. CBSE has officially acknowledged the issue and clarified that the authenticity of the exam was not compromised. Here is everything you need to know about why there’s a QR code on the CBSE question papers.
SurveyWhy do CBSE question papers have QR code?
The CBSE started including QR codes on its question papers, starting in 2018. These were included to ensure the security and traceability of each exam paper. Each code contains encrypted information, such as the specific examination centre and the paper’s set number. This makes it much easier for the board to trace a paperback to its source if it is leaked or photographed. Moreover, by scanning these codes, the authorities can also instantly identify exactly where and when a paper was released.

The QR code also helps the board to identify real-time attendance updates. When the QR code is scanned while handing out the exam paper to the students, the board receives data from it. Later, it can be compiled to check how many students have appeared for a specific subject across the country.
Other than that, the QR code also helps the board to keep an account for every single sheet printed, as the unused question papers are also scanned.

CBSE’s response to the issue
The Central Board of Secondary Education (CBSE) was quick to respond to the QR code controversy. The board has recently released a statement on their official X (formerly Twitter) handle where they acknowledged the issue and clarified that the authenticity of the exam was not compromised. The board also assured parents and students that the issues raised by the students and the parents have been taken seriously and necessary steps will be taken to avoid the problem in the future.

As for how this controversy could have happened? We are guessing that this could likely be because of an expired domain or a URL redirect that someone snatched up. When you have thousands of QR codes pointing to a specific web address and then let that registration lapse, anyone can buy it and point it wherever they want. In this case, someone, with a mischievous intent, clearly decided that Rick Astley was the only appropriate destination for a room full of stressed-out students.

However, if that’s not the case, it could be a classic example of human error, where an employee may have copied the wrong link and directed it to the QR code.
