<p>I bought TPR but it only had 2 practice tests. Although some users said its practice tests were close to the real deal, all of these comments were really old and I do not know whether they still apply. <em>I don't think so personally since I heard that the tests are getting pretty tough lately</em></p>
<p>So I am vacillating among these three: AP Cliffs 5 practice tests, Barrons, Kaplan. I heard that Barrons are much more difficult than the real tests but I don't think overpreparing will kill. Only a few recommend Kaplan and AP Cliffs Practice tests received good review on amazon.</p>
<p>Which should I buy? Thanks in advance.</p>
