I just finished my Environment and Humanity Dantes test (5/28/09) and I scored a 52. Passing score is 46. I barely got by. This book hints at some important topics in the test, but misses a lot of questions. I used the book in conjunction with Wikipedia and other online sources. The book gave me a good guideline for researching topics online. I could recommend doing this, but I didn't use a text book and I barely passed. If you want to exceed at this test, buy a text book. If you want to get by, use this book with online resources.
