Practice Test scores vs. Real Test score

<p>I'm just wondering because I'm starting to get really worried about the subject test that I am taking in a week, World History, do the prep books purposely make the tests difficult in order to make the real one seem easy? So far these are my scores:</p>

<p>Princeton 1 - 710
Kaplan 1 - 680
CB Released 1 - 790</p>

<p>The prep book scores make me doubt myself and I feel as if I can't get 750+. I took AP World History this year and was completely fine for that test... Thanks for the advice.</p>

<p>Well, I’d say that the practice test makes can’t make it exactly the same difficulty, and they would have people complain that what they studied for was much more difficult than the actual test rather than saying the practice tests didn’t prepare them at all. Also I’ve noticed that the AP tests are harder than their corresponding subject tests. If you got a 790 on a CB released test, you’ll be fine.</p>
