<p>Alright for the past few weeks I have been just browsing the site and didn't feel the need to register. But I came across this thread :
<a href="http://talk.collegeconfidential.com/sat-preparation/538932-what-sat-prep-book-should-i-get-ultimate-answer-thread-sat-book-reviews.html%5B/url%5D">http://talk.collegeconfidential.com/sat-preparation/538932-what-sat-prep-book-should-i-get-ultimate-answer-thread-sat-book-reviews.html</a></p>
<p>And it said it recommended Gruber, but when I went on amazon I found link directing me too 'Gruber the complete SAT Guide..' 'Gruber 2400..' 'Gruber Math/reading/writing'..</p>
<p>My question is: is the 'Gruber Complete SAT' a cumulative of all the others, hence the complete, or are the other more in depth? I would just like to know the difference between all those books. </p>
<p>ALSO, before I get berated for asking my question here instead of the thread which recommended the book, I would just like to point out all the unanswered questions in the thread---so I'm posting it here:)</p>
