While in law school in the late ’70s, Scott Hatch taught LSAT preparation courses throughout Southern California to pay for his education. He was so good at it that after graduation, he went out on his own. Using materials he developed himself, he prepared thousands of anx- ious potential test-takers for the SAT, ACT, PSAT, LSAT, GRE, and GMAT. Years ago, Lisa took one of Scott’s LSAT preparation courses at the University of Colorado and improved her love life as well as her LSAT score. Lisa’s love for instructing and writing allowed her to fit right in with Scott’s lifestyle, teaching courses and preparing course materi- als. They married shortly thereafter. Since then, Scott and Lisa have taught test preparation to students worldwide. Currently over 300 universities and colleges offer their courses online and through live lectures, and the Hatches have written the curriculum for both formats. The company they have built together, the Center for Legal Studies, provides not only standardized test preparation courses but also courses for those who desire careers in the field of law, including paralegals, legal secretaries, legal investigators, victim advocates, and legal nurse consultants. Scott has presented standardized test preparation courses since 1979. He is listed in Who’s Who in California andWho’s Who Among Students in American Colleges and Universities,and he was named one of the Outstanding Young Men of America by the United States Jaycees. He was a contributing editor to The Judicial Profiler(McGraw-Hill) and the Colorado Law Annotated(West/Lawyers Co-op) series, and he was editor of several award-winning publica- tions. He received his undergraduate degree from the University of Colorado and his Juris Doctorate from Southwestern University School of Law. Lisa has been teaching legal certificate and standardized test preparation courses since 1987. She graduated with honors in English from the University of Puget Sound, and she received her master’s degree from California State University. She and Scott have co-authored numer- ous law and standardized test texts, including Paralegal Procedures and Practices,published by West Thomson Publishing, and SAT II U.S. History For Dummies, SAT II Biology For Dummies,SAT II Math For Dummies, and Paralegal Career For Dummies,published by Wiley Publishing. 01_596535 ffirs.qxd 8/2/06 10:44 PM Page iv 01_596535 ffirs.qxd 8/2/06 10:44 PM Page v Dedication We dedicate our For Dummies books to Alison, Andrew, Zachary, and Zoe Hatch. They demonstrated extreme patience, understanding, and assistance while we wrote this book, and we appreciate them beyond expression. Authors’ Acknowledgments This book would not be possible without the extensive research and writing contributions of standardized test prep experts David Newland, M.A., J.D, and Benjamin A. Saypol, M.A. Their efforts greatly enhanced our writing, editing, and organization, and we are deeply grateful to them. We’d also like to thank the staff of the Center for Legal Studies, who worked diligently to execute a smooth process in the administrative tasks necessary to bring about this book. We need to acknowledge the input of the thousands of prospective MBA students and other college applicants who have completed our test preparation courses over the last twenty-six years. The classroom and online contributions offered by these eager learners have provided us with lots of information about which areas require the greatest amount of preparation. Their input is the reason we’re able to produce accurate and up-to-date test preparation. Our meticulous scholarship and attempts at wit were greatly facilitated by the editing profes- sionals at Wiley Publishing. Our thanks go out to Tim Gallan and Natalie Harris for their patience and support throughout the process, David Herzog and Laura Nussbaum for their attention to detail during the editing process, and Kathy Cox for getting the project up and running. Finally, we wish to acknowledge our literary agent, Margo Maley Hutchinson at Waterside Productions in Cardiff, for her assistance and for introducing us to the innovative For Dummies series. We thrive on feedback from our students and encourage our readers to pro- vide comments and critiques at [email protected]. 01_596535 ffirs.qxd 8/2/06 10:44 PM Page vi Publisher’s Acknowledgments We’re proud of this book; please send us your comments through our Dummies online registration form located at www.dummies.com/register/.
