The National Institute of Open Schooling (NIOS) has officially revised the exam timetable for its Secondary (Class 10) and Senior Secondary (Class 12) public examinations for the October–November 2025 session. Moreover, this update is important for all NIOS learners, as some papers were earlier postponed due to election-related arrangements and administrative requirements at several exam centres.
