<p>I've been on this forum for a while, and it seems like in the past month wherever I see book suggestions the Kaplan prep book is always in the lead. Why is this one so popular? Previously I'd see a mixture of various books, but now everybody posting recommends Kaplan. </p>
<p>It helped me go from a 2040 on SAT to scoring constant 230s on PSATs. Basically its word list is phenomenal, its math coverage is superb, and the grammar lessons couldn't be better. </p>
<p>It's just an all around great book that has everything needed to boost your score.</p>
<p>Well, I agree that it is quite good. Yeah, the grammar is very very helpful (they give you 15 most common sentence correction questions, 15 most common 15 most common identifying errors questions). After I learned those, my score went up to the 700's (and yes, the errors they predict are actually VERY accurate, i.e. parallelism, pronoun shift, faulty comparison, etc.) After more practice, it becomes extreemly easy. I also think they have a good method for the essay and practice can always help. Seriously, you can spend 2 days with this stuff and increase your score from a 500 to a 650.</p>
<p>I really enjoy the way they do math. They have a basic math section, where all of the more basic topics are covered, and then there are practice questions (which tell you what concept you are working with). Then they have the same for advanced math topics. Then, my favorite, a math traps section!!!!! This accounts for a large part of all the little tricks College Board uses on hard questions and can be very useful to get those hard questions right! Then in the back is the 100 math concepts that you "need to know". </p>
<p>The CR stratagies are good and although the practice might not be entirely realistic, it trains you very well. The word list is a plus and there's a root list also.</p>
<p>And 4 practice tests? What can I say, it's a solid book.</p>
<p>If you use it with Blue Book, and you score isn't very high already, your score will go up.</p>
<p>I would not suggest Kaplan, because the test format seems similar to real one, but in real SAT, the test format will be different from what you have practiced in Kaplan books. </p>
<p>So, only Bluebook can be validated, I think.</p>
