Dr Chung SAT Math for 800?

<p>Is this book good? I'm taking the SAT in two weeks. I'm in the high 700's range, missing 1-2 questions, depending on the test. I've gotten an 800 once (and most recently) but I want to make sure I don't make errors on the real test.
I want to take a couple practice tests to make sure I can get the 800 on the real test. I've already taken all the collegeboard tests.</p>

<p>Are the questions on Dr. Chung practice tests like those of the real SAT?</p>
