What's inside
The board pattern
Part I is compulsory (20 marks). Part II has Sections A, B and C with the ISC choice of questions: Boolean algebra and logic, Java programs, inheritance, data structures, linked lists and binary trees.
Working you can follow
K-map groupings, truth tables, step-by-step stack traces for infix, prefix and postfix conversions, tree traversals written out in full, and complete Java programs with sample input and output.
Checked by computer
Every K-map, truth table, conversion and tree answer is checked by a program, and every Java program is compiled and run before the book is built.
Board-paper analysis
Each answer names the syllabus topic it tests and the years that topic came up in the ISC papers from 2017 to 2026. A chapter shows marks by topic, year by year.
