<p>How much of the modern physics chapter (the last one) do we need to know?</p>
<p>umm understand all of it, its not really that much material… I guess i have a legup b/c i have spent the last 2 weeks doing modern physics in chemistry AP lol… right before the SAT II test… hehe</p>
<p>I just finished studying all of it. It’s only a few concepts and a bunch of equations.</p>
<p>It’s important for like 1 or 2 questions on the test. That book got me an 800 though.</p>
