The Central Board of Secondary Education (CBSE) releases the datesheet for the Class 12 supplementary exams for 2026. According to reports from India Today and NDTV, the supplementary examinations are scheduled for a single day—July 28, 2026. The datesheet is presented as applying to all subjects, with no separate day-wise schedule mentioned for different disciplines. Students who have to appear for the Class 12 supplementary exams can refer to the official datesheet for the exact timetable details. NDTV specifically notes that the CBSE Class 12 supplementary exam will be held on July 28, 2026, for all subjects, while India Today similarly reports that the supplementary exam schedule is published with all exams conducted on that date. The reports indicate that the board is consolidating the supplementary testing into one day rather than spreading it across multiple exam dates.
