This book contains 10 AMC 10 -style tests (problems and solutions). The author tried hard to create each test similar to real AMC 10 exams. Some of the problems in this book were inspired by problems from American Mathematics Competitions 10 and China Math Contest. The author also tried hard to create some new problems. We field tested the problems in this book with students in our 2015 Mathcounts State Competition Training Groups. We would like to thank them for the valuable suggestions and corrections. We tried our best to avoid any mistakes and typos. If you see any mistakes or typos, please contact [email protected] so we can make improvements to the book. This book now is volume 6 of the AMC 10 series: https: //www.amazon.com/gp/aw/d/1530036690/ref=cm_cr_srp_mb_bdcrb_top?ie=UTF8

This is the second edition of the book of American Mathematics Competitions 8 Practice containing ten sets of AMC 8 style tests. This edition also made all the corrections to some errors in the first edition. All problems have the detailed solutions. Good luck
