When studying for an examination, the most effective approach is to closely simulate the behavior you'll ultimately be required to perform. For the SAT, then, the most effective strategy to get that 800 will be to simulate the harder questions on the test. We have analyzed all 6 released College Board tests, every Khan Academy question, and talked to many students who have already given the new SAT. We then sat down and got to work to develop questions that would be challenging and help the student master the difficult questions. These are the questions that separate the 700 scoring student from the 800 scoring student. We made sure to not make the questions overly difficult because questions like that are useless. Our questions for this book are as close to the difficult questions on the real SAT as possible. This is a must have book for any student aiming for the perfect 800 score.
