Does the Kaplan 2400 book go over all types of hard SAT math questions?

<p>I have the Kaplan SAT Strategies, Practice and Review 2011 Edition and I found that it was pretty useful. So far, the only thing that has bugged me was that the practice section on traps used on the SAT didn’t have the answers explained. Instead, they just directed you to the trap tip # to figure it out on your own. Other than that, the book explains why the answer is correct and why the others are incorrect pretty thoroughly. Not to mention it has tons of practice in it, which is always a plus!</p>
