Complete guide to CBSE Class 10 second exam (May 2027). Who should take it, best-of-two rules, subjects to improve, registration process, and data-driven decision framework to help you decide.
In short: CBSE offers a second exam in May for Class 10 students who want to improve their February scores. In 2026, 6.69 lakh students took it — 78% for score improvement, not compartment. The best-of-two rule means your higher score counts. Take the second exam if: you scored 10+ marks below your potential in a subject, you have time to prepare, and the subject matters for your stream choice. Don't take it just because it's available.
