The National Testing Agency (NTA) has officially cancelled the NEET UG 2026 exam, which was held on May 3, following allegations of a significant question paper leak. Investigations by the Rajasthan Police Special Operations Group (SOG) revealed that a 'guess paper' containing approximately 410 questions was circulated via WhatsApp and Telegram, with about 135-140 questions found to be identical to those in the actual exam, primarily in the Biology and Chemistry sections. This leak reportedly surfaced in Sikar, Rajasthan, just 42 hours before the exam and was sold for prices ranging from ₹20,000 to ₹5 lakh per student. The Central Government has initiated a CBI probe to ensure a transparent investigation, leading to the detention of at least 13 suspects linked to coaching networks. This incident is not an isolated case; the NEET exam has faced similar controversies in previous years, including massive protests and allegations of organized leaks in 2024 and 2017. Critics point to systemic gaps in security, crisis response, and administrative practices that continue to compromise the integrity of the examination process. The cancellation affects over 25 lakh medical aspirants, leading to immense stress and uncertainty as they await new examination dates from the NTA.
