<p>Hey guys, I just wanted to know how hard the Physics SAT 2 was and what type of material I should REALLY know on the test. Also is Barrons (the book I have been using for a month and a half now) really a good book. I mean the practice test are scary because they are really hard. So I guess I want to know if the book is harder then the test. THanks in advance!!!!</p>
<p>Barrons books are ALWAYS-and i mean ALWAYS- harder than the actual tests. The Physics SAT2 covers everything, so you have to know everything. Seriously.</p>
<p>@ anyone who's taken the test: Do we have to know theory of relativity, radioactivity, atom models [basically modern physics]?</p>
<p>Yes. There are 1-2 questions on each of those you listed</p>
