The National Testing Agency (NTA) is facing intense scrutiny following revelations that all Chemistry questions on the NEET UG 2026 exam were identical to those found in a circulated 'guess paper'. This stark match has triggered a multi-agency investigation, leading to the cancellation of the exam and a subsequent re-examination for over 22 lakh students. The NTA has since referred the implicated Chemistry paper setters and translators to the Central Bureau of Investigation (CBI).
Internal Probe Reveals Exact Match
An internal inquiry by the NTA, prompted by a whistleblower's email received on May 7, discovered that the Chemistry section of the NEET UG exam, conducted on May 3, had been compromised. The extent of the alleged leak was such that every single Chemistry question appeared in a 'guess paper' that had been circulated prior to the exam. Sources close to the development indicate that the NTA has now replaced all question setters and translators for not only Chemistry but also for Biology and Physics for the rescheduled examination.

Whistleblower and Spread of Suspect Material
The investigation gained momentum after an email, sent by a whistleblower in Sikar, Rajasthan, on May 7, flagged potential irregularities. This whistleblower subsequently provided a PDF of the compromised paper. Reports suggest that parts of the Biology paper may also have been partially leaked. The suspect material, described as a 150-page PDF containing around 400 questions, had reportedly gone viral on social media and WhatsApp groups, with some instances of distribution occurring as late as 42 hours before the exam commenced.
Rajasthan Police and CBI Involvement
The Rajasthan Police Special Operations Group (SOG) has been actively investigating these claims. Early findings from the SOG indicated a significant overlap, with sources claiming that nearly 150 questions from a student-shared question bank matched the actual NEET paper. While initial statements from the SOG acknowledged the investigation into a potential 'guess paper' match with numerous questions, claims of a definitive paper leak were at that point considered speculative. However, the severity of the findings, particularly the 100% match in Chemistry, has since led to a broader CBI probe. The CBI has reportedly arrested MBBS students and doctors allegedly involved in a 'private mafia' WhatsApp network.

NTA's Response and Institutional Changes
In response to the escalating controversy, the NTA has undertaken significant internal restructuring. Beyond replacing question setters and translators, the agency is also focused on strengthening its leadership team, advertising for professional roles such as Chief Technology Officer and Chief Financial Officer. The NTA has publicly defended its security measures for the May 3 examination, which included GPS-tracked vehicles with watermarks, AI-assisted CCTV surveillance, and 5G jammers. However, the agency acknowledged receiving information concerning alleged malpractice only on the late evening of May 7, four days after the examination.
Broader Implications and Student Impact
The NEET UG examination, India's primary gateway for undergraduate medical admissions, was held across 551 cities in India and 14 international centers. The cancellation has directly affected over 22.7 lakh aspirants, creating significant stress and uncertainty regarding their academic futures. Education experts have pointed out that such disruptions disproportionately impact students from less privileged backgrounds. Protests have been staged demanding accountability, with calls for the resignation of the Education Minister. The Union government is reportedly considering a hybrid examination model for future NEET cycles in light of these repeated integrity issues.
