Your book is "fabulous". I spent two hours last night working problems from it. I'm planning to use some in what I do with teachers, with citation of course. I love it. I love the clever problems you came up with and the clever solutions of the MATHCOUNTS problems you used. Dr. Harold Reiter, former Chairman of Mathcounts Question Written Committee, Math Professor, UNC at Charlotte Being responsible for the publications we put out at MATHCOUNTS, I understand the incredible amount of work this required. Congratulations on such a great accomplishment. ---Kristen Chandler Mathcounts, Deputy Director & Program Director I just finished going through with it. As for the book, I'm pretty impressed. It really seems you put a lot of time and effort into it, and I liked it. - Calvin Deng 2010 USA IMO Team Member, Silver Medalist I bought this book together with "Twenty More Problem Solving Skills" for my 6th grade daughter, who loves math, and is preparing for AMC and MathCounts competition. She is very excited with these two books, and learns a lot from these two books in her math competitionpreparation. We recommend this book as a must have math competition collection. - -A parent
