<p>from my experience, the math section on the princeton review practice tests is harder than the real thing, but the writing/critical reading is easier than the real SAT</p>
<p>I guess Barron's will serve for both CR and Math in terms of questions being harder. I've heard a lot about Grammatix out here in CC, haven't tried it yet, but think it can be a great deal too.</p>
<p>The old "10 Real SATs" has good CR practice passages. They can be bought used starting at approximately 25 cents (white book) and $2.50 (red book) plus shipping on used books on Amazon. Can't use them for scoring because they have analogies in the CR sections. But, lots of reading passage practice -- written by the real test writers.</p>
<p>spiffystars--although i advice many the same thing u just said, I myself find it pretty disturbing to search for something, since most of the times I forget what I was searching for when I start reading some other interesting post! :) However when it's simply NECESSITY, I rely on browsing a bit (but till now hardly I faced situations like that)</p>
