The National Testing Agency (NTA) canceled the NEET UG 2026 examination after allegations surfaced regarding a widespread paper leak [1].

The cancellation disrupts the medical school admission cycle for thousands of students and raises critical questions about the security of India's high-stakes national testing infrastructure.

The exam took place on May 3, 2026 [1]. Following the test, reports emerged of a “guess paper” circulating among students that allegedly contained about 120 questions from the actual exam [2]. These leaks were primarily centered in the Sikar district of Rajasthan, while the suspected printing source was located in Jaipur [3].

According to official records, the NTA received inputs regarding malpractice on May 7, 2026 [2]. The agency escalated the matter to central investigative agencies on May 8, 2026 [2]. With the approval of the Government of India, the NTA subsequently voided the results to maintain the integrity of the selection process [1].

The Central Bureau of Investigation (CBI) has been tasked with probing the scam [1]. Investigators are focusing on how the leaked materials were produced and distributed within Rajasthan. The probe aims to identify the individuals responsible for the breach and determine if the leak was systemic or isolated to specific coaching hubs [3].

Protests erupted following the initial reports of the leak, as students expressed concerns over the fairness of the competition. The government's decision to cancel the exam reflects the scale of the alleged breach, specifically the volume of questions leaked, which made it impossible to verify the legitimacy of the scores [2].

“The National Testing Agency (NTA) canceled the NEET UG 2026 examination after allegations surfaced regarding a widespread paper leak.”

The cancellation of the NEET UG 2026 exam underscores a recurring vulnerability in India's centralized testing system. By involving the CBI, the government is signaling a zero-tolerance approach to exam fraud, yet the incident highlights the immense pressure on the NTA to secure digital and physical assets against organized leaks in regional education hubs.
