<p>Or do they cover pretty much the same thing</p>
<p>A lot of stuff overlaps, but Physics SAT doesn’t test on liquids, and Physics B doesn’t test on stuff like rotational kinematics or space stuff (like that thing about red shift).</p>
<p>I took Physics B and got a 3. I took the Physics SAT 3 times; my scores were 580, 600, and 680. (Yeah, my scores suck)</p>
<p>From what I remember, Physics B covers everything on the SAT II. That said, you should probably take a couple practice tests to make sure.</p>
