<p>Euuhhh…I guess Princeton Review, but I usually try to avoid fake tests whenever possible. In addition to the real tests I listed, I have SAT students do real PSATs (if their scores are below 680 or so) or even real GREs and LSATs (if their scores are in the 700s). </p>
<p>One another thing about PR: while the tests are worthwhile practice (in that the questions are not usually arbitrary), the scoring is unreliable. So if you use PR, don’t worry much about your scores; just try to work through the questions and learn as much as you can.</p>
<p>Flaky as the SAT and GRE can be, they are at least subject to the Fairness in Testing Act. Fake tests can definitely help raise scores, but they should be a last resort.</p>
