<p>Of the three, Kaplans, PR, and Barron's, which has the hardest practice test??? I got 60 on Kaplans, 48 on Barrons and like 43 on Princetons.......But with the Barron's one, I took it after taking Princeton's and Kaplan's at 12:00 am so I was pretty exhausted...</p>
<p>PR one was much harder than barron's (I took APWH last year)</p>
<p>If you get over 50 on PR, you are pretty much guaranteed to ace the actual exam.</p>
