The National Testing Agency (NTA) has announced that the re-examination for the National Eligibility cum Entrance Test Undergraduate (NEET UG) 2026 will take place on June 21, 2026. This decision comes after the initial exam, held on May 3, was canceled due to a significant paper leak controversy. Investigations revealed that a leaked 'guess paper' had a striking overlap of 120 to 140 questions with the actual exam, prompting concerns about the integrity of the testing process. The NTA's announcement was made via their official social media channels, and they have urged candidates and parents to rely solely on official updates. The investigation into the leak, which has implicated coaching centers and middlemen in various states including Rajasthan, Maharashtra, Haryana, Bihar, and Kerala, has been escalated to the Central Bureau of Investigation (CBI). The cancellation of the exam has impacted approximately 23 lakh medical aspirants, marking a significant disruption in India's medical entrance examination history.
