Checked against the official CBSE pages on 3 November 2026. 2026-27 is the latest curriculum CBSE has published.

CBSE says: "The assessment scheme will be similar to class XII Board examination and shall be carried out at school level." CBSE does not hold a Class 11 board exam, and it does not publish Class 11 sample papers, past papers or a date sheet.
