CBSE Class 10 Mathematics 2018 leak — re-exam waived

Stalled documented status: FIR registered

Confidence C — based on the press record (archived below). No primary documents on file yet; treat names of agencies, dates and figures as reported, not established.

The Class 10 Mathematics paper leaked alongside the Class 12 Economics paper in the March 2018 CBSE breach, circulating on WhatsApp the night before. CBSE first announced a re-exam for both, then withdrew the Class 10 re-test in April 2018, saying its inquiries showed the leak was confined to a few beneficiaries in Delhi-NCR and Haryana. About 16 lakh students' results stood on the leaked paper; the criminal case proceeded with the Economics-paper docket.
