An Excursion In Mathematics

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 is very helpful for isi , cmi also

A very good book for math olympiads, foundation for iitjee, isi etc exams. Good packaging also. Received the latest edition.

Great book for mathematics Olympiad.

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.
