CBSE Class 12 Computer Science Sample Papers 2026-27

Build complete board readiness for CBSE Class XII Computer Science with 15 fully solved, independently verified sample papers covering Python, SQL, Data Structures, File Handling, Networking, and Societal Impact of IT, each modelled on the current CBSE five-section paper pattern.

Each paper follows the standard format across five sections, Section A (objective and Assertion-Reason, 21 marks), Section B (very short answer, 14 marks), Section C (short answer and SQL, 9 marks), Section D (case-based, 16 marks), and Section E (long answer and networking, 10 marks), for 70 marks in 3 hours.

What's inside:

• 15 complete papers across Easy (Papers 1 to 5), Moderate (Papers 6 to 10), and Difficult (Papers 11 to 15) levels, building from single-concept questions to multi-layered programming, complex SQL chains, and recursive algorithms

• Python programming questions in every paper covering functions, exception handling, recursion, file handling (text, binary, and CSV), and Python-SQL database connectivity, with every program independently traced and verified

• SQL questions in every paper covering SELECT, WHERE, GROUP BY, HAVING, ORDER BY, JOIN, and multi-clause combined queries, progressing to three-table joins and complex aggregation in the Difficult papers

• Data Structures questions in every paper covering stack and queue implementation using lists, with progressively harder combinations including recursion, exception handling, and file integration

• Networking case studies in every paper covering topologies, devices, server placement, VLAN, NAT, WAN redundancy, and cyber safety

• Marking scheme breakdowns with every answer, separating logic marks, syntax marks, and output marks question by question, so you understand exactly how partial credit is awarded

How to use it: Attempt each paper under strict exam conditions (3 hours) before checking the answer key. Work through Easy papers to build concept recall and coding fluency, then progress to Moderate and Difficult papers to develop the multi-concept problem-solving speed needed on exam day.
