This book is designed towards mastering the CogAT from which many school districts identify gifted children for admissions into their gifted and talented programs. The book contains 9 lessons, one for each subtest. Each lesson consists of three main parts: Description of the question type, exercise questions, and answers and explanations.In addition, the book has 2 full-length practice tests with detailed explanations. It is recommended that you take the first practice test as a diagnostic test to understand your current level of expertise and in which area you need improvement. After completing the 9 lessons, use the second practice test to help improve your problem solving skills. There is no greater substitute than to study and practice.After completing any lesson or test, immediately use the answer key and explanations to check your answers. Review all answers. Take the time to carefully read the explanations of questions you got incorrect. If you find yourself continually missing the same type of questions, review the lesson that matches the same type of question again.
