What's inside
Two levels of difficulty
Level 1 covers the full ISC Computer Science Paper I syllabus — every topic, every subtlety. Level 2 is harder: the same syllabus, but with questions designed to expose assumptions and gaps.
Harder than it looks
Every question has at least one plausible wrong answer. Options are chosen to match the most common misconceptions about Java — not random distractors, but the mistakes students actually make.
Full explanations
Every answer comes with a detailed explanation: why the correct option is right, why each wrong option is wrong, and step-by-step traces for questions involving loops, recursion, or inheritance.
Checked by computer
Every question is compiled and run. The stated output is the real output from the Java compiler, so there are no errors in the book.
