The National Testing Agency cancelled the NEET UG 2026 undergraduate medical entrance examination following allegations of a massive paper leak [1].

The cancellation affects over 22 lakh candidates [4] and undermines the integrity of one of India's most competitive professional gateways. Because the exam determines entry into medical schools nationwide, the breach has sparked a high-level federal investigation.

The exam took place on May 3, 2026 [1]. Authorities discovered that a circulated "guess paper" in Rajasthan matched approximately 120 chemistry questions [2] out of the 180 total questions on the test [3]. Evidence suggests the question bank was sold and shared across social media platforms a week before the exam date [1].

The Central Bureau of Investigation has launched a probe into the leak. Investigators believe the breach originated in Nashik, Maharashtra, before spreading to Rajasthan [2].

In a coordinated effort, Nashik police detained one man at the request of Rajasthan authorities [5]. The suspect is being questioned to determine how the secure materials were accessed and distributed to candidates.

The NTA has scrapped the results and said that a re-examination will be conducted soon [1]. This decision follows a growing outcry from students and parents regarding the fairness of the testing process.

The scale of this leak—affecting roughly two-thirds of the total questions—suggests a systemic failure in the NTA's security protocols rather than an isolated incident. By involving the CBI and coordinating arrests across state lines, the Indian government is attempting to signal a zero-tolerance approach to exam fraud, but the necessity of a re-exam creates significant psychological and financial strain for millions of students.
