Questions of Algebra, Combinatorics, Geometry and Number theory are asked preferably in RMO, INMO, and IMO, with the ascending difficulty level.

Reference books for INMO Preparation

The Indian National Maths Olympiad (INMO) is one of the most prestigious examinations at the college level. The problems asked in INMO are quite challenging. The students can guesstimate the difficulty level of the exam as they are expected to solve only about 6 problems over a period of 4 hours. But the students need not worry as we have a list of some reference books for the preparation of the International Maths Olympiad (INMO), which will help you provide a good insight into the concepts and clear your doubts in every concept. 

Mathematical Circles by Dimitri Fomin

The first book on the list is "Mathematical Circles by Dimitri Fomin". This is an essential book for beginners as it gives a very good insight into some concepts. This is a beautiful book to begin your Olympiad Journey. Even if you have a fair bit of knowledge, it is recommended that you read this book.

An Excursion in Mathematics

The second book on the list is very famous among the students preparing for INMO which is "An Excursion in Mathematics." It is a comprehensive book for the Olympiads. This book has all the content that you will require. All INMO qualifiers receive this book as an award.

Problem-Solving Strategies by Arthur Engel

The third and the last book on the list is "Problem-Solving Strategies by Arthur Engel." This is a great book for the advanced reader. This book aims at giving an insight into techniques used to solve the problem. Every chapter is dedicated to one specific technique and contains some problems directly from the International Maths Olympiad. This book is a boon to the students preparing for INMO.
