<p>I am a freshman moving to ap PSI physics B next yr. Have taken PSI physics honors before. Do i need to take Physics C to take the subject test? Since u can't use calculators, are the conceptual questions easy. How is the multiple choice to AP similar and differnt.</p>
<p>No 0 physics C needed. IT’s all B plus some extra stuff like time relativity.</p>
<p>The conceptual questions on the subject test are very easy (wayyy easier than Physics C, and also easier than Physics B). They require no Physics C or calculus; however, they do require knowledge of all the topics on Physics B, and a few more such as contemporary physics, special relativity, and a couple other things. Physics B actually prepares you better for the subject test than would the Physic C’s alone.</p>
<p>so i NEED to invest in a special subject test book and not just an AP book</p>
<p>Well, you could just identify the stuff that appears on the subject test that’s on the AP and study that.</p>
<p>But I guess an AP book and a subject test book combined can give you a more favorable chance of a high score. But look for a cheap or used subject test prep book.</p>
<p>For a second I thought PSI Physics was pounds per square inch :)</p>
<p>You don’t <em>need</em> any courses of any type to take SAT physics. SAT Physics is a lot easier than Physics C, no calculus required and the conceptual questions are also easier.</p>
<p>well PSI is not pounds per square inch, its Progressive Science Initiative</p>
