Union Education Minister Dharmendra Pradhan on Friday said the government had to take “tough decisions” after irregularities were detected in the conduct of the NEET-UG, asserting that authorities did not want even a single deserving student to lose their rightful seat because of the “examination mafia”.

He also asserted that the government is committed to ensuring that the re-test scheduled to be held on June 21 remains “100 per cent error-free”.
