b) Computer Science Board Paper Pattern 2025-26  Section-wise

The Computer Science paper follows a comprehensive pattern covering programming concepts, database operations, and network fundamentals with both theoretical and practical applications.

Section A: Multiple Choice Questions (20 marks)

• 20 MCQs covering all units with 1 mark each
• Topics include Python syntax, data structures, SQL commands, and networking concepts

Section B: Very Short Answer Questions (14 marks)

• 7 questions worth 2 marks each
• Code snippets analysis, algorithm tracing, and concept definitions

Section C: Short Answer Questions (24 marks)

• 8 questions worth 3 marks each
• Programming logic, database queries, and network protocol explanations

Section D: Long Answer Questions (12 marks)

• 2 questions worth 6 marks each
• Complete program writing, complex database operations, and comprehensive networking solutions

Key topics include: Python Programming, Data Structures (Lists, Stacks, Queues), File Handling, Database Management with SQL, Computer Networks, and Internet protocols.

How Does the Two-Exam Format Affect Computer Science Preparation?

The new format introduces two full exams in a year, requiring a focused and structured preparation plan:

• November Exam (Exam 1): May feature questions based on fundamental programming concepts, basic data structures, and core database operations
• March Exam (Exam 2): Will likely include advanced programming problems, complex SQL queries, and detailed networking concepts

Practising Computer Science Sample Papers 2025-26 Before Exams Helps in:

• Mastering Python programming syntax and logic building
• Understanding code debugging and error identification techniques
• Improving speed in writing SQL queries and database operations
• Building confidence in explaining networking protocols and internet concepts
• Developing problem-solving skills for algorithmic questions
• Getting familiar with practical programming scenarios

How to Use Computer Science Sample Papers 2025-26 Effectively?

• Practice in timed conditions: Especially for programming questions and code analysis
• Focus on clean code writing: In Python programs with proper indentation and comments
• Refer to marking schemes: To understand expected code structure and explanation detail
• Master all three units equally: Ensure balanced preparation across Programming, Database, and Networks
• Practice hands-on coding: Run programs on computer to verify logic and output
• Use sample papers to strengthen SQL query writing: Practice SELECT, INSERT, UPDATE, DELETE operations with different conditions

In conclusion, regular practice with Class 12 Computer Science sample papers is key to mastering the dual-exam format and excelling in both board exams. These papers help you build programming logic, refine your coding skills, and gain confidence in tackling both theoretical concepts and practical implementations. Until the official 2025–26 papers are released, make use of previous years' papers and trusted resources like Educart to stay ahead.
