Which controversies have hit NEET exam in the past?

The NTA on Tuesday cancelled the NEET UG 2026 exam due to a paper leak, a step that will impact around 22 lakh students. In 2024, an FIR was filed in Bihar after it was found that students allegedly paid ₹30-50 lakh for the question paper. From 2020-2021, NEET was hit by 'solver gangs' scamsters who appeared instead of students.
