Written by a MATHCOUNTS state champion, this book contains more than 400 carefully selected problems ranging from MathCounts to the International Math Olympiad, each with a detailed solution. It is intended for advanced MathCounts mathletes, coaches, and parents. Please note that although this book includes many problems from high school math competitions, the purpose of the book is not to prepare for those contests. Rather, these problems are chosen to hone MathCounts problem solving skills because today's high school math problems will appear in tomorrow's MathCounts competitions.
