CBSE had originally penciled it in for 15 July 2026. Somewhere along the way, that plan changed, and the board pushed the date back by nearly two weeks. No fresh notification explaining the delay accompanies the update, just the revised schedule itself, now live for anyone to check.The exam is meant for a specific group of students: those who cleared most of their Class 12 papers but got stuck on one or two subjects, as well as candidates who are retaking a subject simply to improve their score. For context, CBSE announced the main Class 12 results back on 13 May 2026. Students then had until 8 July 2026 to apply for the compartment exam, whether they were studying through a regular school or as private candidates.How To Find Your Date SheetHead to the official CBSE website, cbse.gov.inLook for the link labelled "CBSE Class 12 Supplementary Examination Date Sheet 2026"Click it, and a PDF will load right on your screenScroll through to find your subject, exam date, and reporting timeSave or download the file so you're not scrambling to find it again laterOne detail that might surprise a few readers: this date sheet isn't limited to the standard academic lineup like Physics, History, or Accountancy.
