<p>I only had Honors Chemistry and won't have AP Chem in time for the SAT II Chem test, so I've decided to use Barron's for its thoroughness and then PR for light review. However, I'd like not to stress myself out with info I won't need to know, especially since I'll have to review material from a year earlier + learn more info. Are there certain concepts or chapters that are better left untouched? What chapters have very little in the actual test?</p>
<p>And what should I particularly emphasize in my studies?</p>
<p>Thanks for your time!</p>
