Hello,

The Central Board of Secondary Education (CBSE) has released the official sample question papers for Classes 10 and 12 for all subjects. Students who are preparing for the CBSE Pre-Board Examination 2026 can use these sample papers to understand the latest exam pattern, question types, and marking scheme. CBSE-affiliated schools usually conduct pre-board exams based on the pattern provided in these official sample papers, so referring to them will help students prepare in a more focused and effective manner.

Thank you.
