Class 12 Computer Science

This is your complete, chapter-wise practice hub for Class 12 Computer Science. Every question is aligned to the latest NCERT syllabus and mapped to the exact chapters your school follows, so you can revise in the same order you are taught. Across 7 chapters we have 42 practice questions covering all three difficulty levels — Easy to build confidence, Medium to consolidate, and Hard to stretch you toward competitive-exam command in the senior-secondary years.

Class 12 Computer Science rewards logic, syntax and computational-thinking questions. Each chapter on XamBaaz gives you three separately timed quizzes (Easy, Medium, Hard) with exam-grade marking — +2 for a correct answer, −1 for a wrong one and 0 for a skip — the same negative-marking discipline used in CBSE Board exams. Every question comes with a one-line explanation, so you learn the reasoning behind the answer instead of just memorising the option.

You can start anywhere. Popular starting points include Python Revision and Functions, File Handling, Data Structures: Stack and Queue, all the way through to Society, Law and Ethics (Advanced). Work chapter by chapter, watch your accuracy climb on each one, and once you have attempted every chapter the Class 12 Computer Science Subject Mastery Test unlocks — a 30-question, 60-minute cross-syllabus mock that mirrors a real CBSE Board exams paper.

Practice is completely free to try — no credit card, no app to install. Sign in with Google and your progress, streaks and XP save automatically across every device, so you can revise Class 12 Computer Science on your phone between classes and pick up exactly where you left off.
