This book contains the detailed explanations for every test question in the 2nd edition (and 7 tests in the 1st edition) of "The Official SAT Study Guide" published by the College Board. These explanations include word definitions and great tips which will help you successfully prepare for the SAT.* The Study Hall was founded in 1992 and we have successfully worked with thousands of students, helping them prepare for the SAT. Since we work with these students individually, we get continuous feedback from them. This feedback has been invaluable in developing the explanations to the test questions. You will find a great many beneficial tips, insights, and observations of test tendencies in these explanations. We have included instruction, not just explanation.
