CBSE Class 12 Computer Science 2026 Question Paper & Solutions

The CBSE Class 12 Computer Science marking scheme is designed to reward stepwise accuracy and conceptual clarity.

Main highlights include:

• Stepwise marks for programming/code-based questions
• Recognition for correct logic, code efficiency, and answer presentation
• Structure: 70 marks for theory (programming, data structures, Boolean algebra, databases), and 30 marks for practicals (Python coding tasks)
• Partial marks for partially correct answers

The CBSE Class 12 Computer Science 2026 paper covers the complete syllabus with an emphasis on Python programming, data structures, Boolean algebra, and computer networks.

Syllabus highlights:

• Programming in Python
• Data Structures (Stacks, Queues, Lists)
• Database Management and SQL
• Boolean Algebra
• Computer Networks
• Emerging Trends

The 2026 CBSE Class 12 Computer Science paper was generally rated as moderately difficult.

Key points:

• Balanced mix of easy and moderate questions, with some tough programming/case study items
• Candidates with strong programming and logic skills found the paper manageable
• Application-based problems tested real-world coding abilities

Yes, CBSE releases official answer keys and marking schemes for the Class 12 Computer Science paper.

These include:

• Step-by-step solutions for programming/coding questions
• Detailed explanations of correct concepts and logic
• Sample model answers for long theory questions

You can find CBSE Class 12 Computer Science 2026 solutions on this page under the solutions download link or in the official CBSE answer release.

Solutions usually offer:

• Fully solved coding/programming tasks
• Explanation of logic and stepwise marking
• Complete answers for all theoretical and application-based questions

Solving previous year papers is highly important, but it should be combined with other resources.

For best results:

• Thoroughly study NCERT textbooks
• Practice sample papers and mock tests regularly
• Focus on practical coding exercises
• Understand the latest exam pattern and marking scheme

The CBSE Class 12 Computer Science Board Exam 2026 follows a two-part pattern:

• Section I: Theory (70 marks) – Programming (Python), data structures, Boolean algebra, databases, computer networks
• Section II: Practical (30 marks) – Python coding exercises and output prediction tasks
• Question types include: short answer, long answer, coding, and competency-based problems

The most important chapters in CBSE Class 12 Computer Science are:

• Python Programming and Data Structures (such as stacks, queues, lists)
• Database Management and SQL
• Boolean Algebra
• Computer Networks
• Emerging Trends (as per latest syllabus)

Yes, CBSE board papers for Class 12 Computer Science are primarily based on the NCERT syllabus.

However:

• Some application-based or competency-focused questions test conceptual understanding beyond rote learning
• Practice with both NCERT exercises and sample/previous year papers for complete coverage

While exact questions may not repeat, practicing previous year CBSE Class 12 Computer Science papers helps you:

• Understand important chapters and frequently asked topics
• Get familiar with question trends and paper patterns
• Improve exam readiness by building speed and accuracy

Yes, CBSE examiners give stepwise marking for coding and problem-solving questions.

This benefits students by:

• Awarding marks for partially correct code or logic
• Recognizing every correct step or key point in long answers
• Encouraging clear presentation and detailed workings
