RMO The Practice Book brings together 28 past papers from ten examination years (2013–2019 and 2023–2025), followed by five full-length mock papers. The collection contains 200 questions: 170 past-paper questions and 30 supplementary practice problems.

Worked solutions develop complete proofs step by step, with labelled geometry diagrams and additional methods for selected questions. A yearwise contents list, topic index and alternate-method locator support both paper practice and focused revision.

Prepared for Mathiit’s Mathematics Olympiad Series, this book is intended for students building their problem-solving and proof-writing skills for the Regional Mathematical Olympiad. Original past-paper questions and source solutions are credited to their authors and to HBCSE, TIFR, with a source directory included in the book.
