Acknowledgments
I would like to thank my wife and my two daughters, Kris and Erin, for their
patience and understanding while I was writing this book. This book is dedicated
in tribute to the late Dr. Jerry Bobrow of Bobrow Test Preparation Services, who
was not only my publishing agent but a dear friend for many years. A special
thanks also goes to the many professional and dedicated high school APES
teachers who have contributed to and reviewed this book, making it the finest
book possible.
Barron’s would like to thank Brian Palm for providing his expert advice and
feedback throughout the editorial review process for the AP Environmental
Science, 7th Edition, and for writing several of the Free-Response Questions in
this book and on the online tests.
