<p>WEll in my experience the barron's ap prep books have been much harder than the real test and many i asked agreed with me. However my question is are the barron's sat practice tests harder than the real thing, cos i am not doing so hot on the practice tests.</p>
<p>That's what I've read in the forums here. </p>
<p>The most accurate tests are College Board and Princeton Review.</p>
