<p>Barron's Stat book is good. I got REA last year and didn't use it at all. Instead I sat in front of my dad's laptop for 2 days, ate dark chocolate, and took tons of practice tests. I got a 5. (I had just gotten back from debate nationals and had 4 days to study for 2 tests!)</p>
<p>At the beginning of Barron's, there's a chart of the types of situations you should use which tests in (i.e. if you know pop. std. dev., if you only know sample, etc.) and the conditions. CONDITIONS are important. Know how to use calculator, but know the conditions for the tests as well. Otherwise you won't get full credit. </p>
<p>Search on google. There was a site for AP Stat prep for this one private academy that I used selectively - everything was free, and they had summaries of every type of test/subject/etc. as well as practice tests.</p>
<p>If you have very little time - just have two charts handy - the one from barron's, and one you make yourself (barron's doesn't have all of them) about tests, corresponding forumlas, calculator functions, etc.</p>
<p>Good luck...!</p>
