We would like to express our sincere appreciation to all of those people who have helped to shape this book. First and foremost, we would like to thank all Intermediate and Upper-Intermediate Group test writers between 2000 and 2005. We also owe a special debt to Patricia Bilikmen and Steve Riva who scrupulously proofread and edited the material in the book. We would also like to thank Beth Pogan, Robert West, Gary Conlan and Tahir Onur for their invaluable proofreading. We also thank Nurcihan Karık and Sadiye Aslanbas who formatted the material and Umut Kahraman who created a software program that enabled us to prepare the vocabulary tasks.
