An Excursion In Mathematics Paperback – 1 January 2018

it is very helpful for isi , cmi also

Such a fine book at this price!- no frills, straight theory, examples, problem set- contains ANSWERS & HINTS to ALL problem sets- great selection of question, examplesGet this book as well as Challenges & Thrills of Pre-College Math (has 30% solutions), Pathfinder (Tiwari/Seshan) (doesn't have solutions for proof based, numericals only) & Indian National Mathematics Olympiad (Manocha) (has a lot of solutions!) you are pretty much set for RMO & to some extent INMO.

It has got good problems and so much resources at the back of the book a good arranged content but bad explanations

Nice.

Slim but comprehensive. Other than the maths, it also gives you a nice idea of the olympiads, and provides a list of other olympiad books.

Book is small, compact and they kept it simple. I would not use it as book to start new topics like number theory, combinatorics. It's an excellent book for those students who are already familiar to the concepts.Next thing, it contains many years of rmo and inmo questions papers and every part has its own exercise(like ncert) containing 15-20 questions.A good book to read just before exam.

THIS BOOK IS HC VERMA OF OLYMPIAD MATHEMATICS💖♾️🇮🇳.

Best book but is at cost of 150 from Pune. But the cost is kept on amazon at 400, that is not selling that is called looting, within india.
