A complete match between a leaked guess paper and the actual Chemistry questions in this year's National Eligibility cum Entrance Test (NEET) has prompted the National Testing Agency (NTA) to refer all Chemistry paper setters and translators to the Central Bureau of Investigation (CBI). The investigation was initiated after a whistleblower from Sikar reported the leak on May 7, four days post-exam. The NTA discovered that every Chemistry question had been compromised, with some Biology questions also partially leaked. A total of 26 to 27 individuals, including 24 translators and 3 paper setters, are now under scrutiny. Notably, PV Kulkarni, a retired lecturer from Pune, has already been arrested for his role in setting and translating the paper. In response to the incident, the NTA is overhauling its protocols, including replacing all question setters and translators for the retest scheduled for June 21. Education Minister Dharmendra Pradhan has called for tighter security measures and coordination with local authorities to ensure the integrity of future examinations.
