Computer Science Class 12 CBSE Sample Paper 2025-26

New Paper pattern for Sample Paper Computer Science Class 12 Session 2025-26

The Board is introducing changes to Examination and Assessment practices to align assessment to Competency Focused Education, with a greater number of Competency Based Questions or questions that assess the application of concepts in real-life situations.

So let us review the previous year as well as the current year’s assessment and evaluation practices to be followed by the board.

Question Types	2025-26	2025-26
Competency-based questions	30% in the form of Multiple Choice, Case-Based Questions, Source Based Integrated Questions or any other type	40% in the form of MCQs/Case Based Questions, Source-based Integrated Questions or any other type
Objective type questions	20%	20% – Response Type Questions (MCQ)
Short Answer/Long Answer Questions	50%	40% – Constructed Response Type
