<p>I'm retaking my SAT II Chem in the fall(got a 720) aiming for 750+. I was in AP Chem this year and did really well, but didn't study for SATs and the questions are really different. I had Princeton Review and did some released tests. I have the most trouble with the "random" questions, like which element galvanizes steel, which is a semiconductor, etc. How on earth do you prepare for those kinds of questions? Which books should I get?</p>
<p>Anybody? :D</p>
<p>Those questions are pretty much memorizable, and they are really dumb, don’t really test knowledge. For example, which element galvanizes steel, its Zinc (If you ever heard of zinc galvanized nails, i know its a stretch). Then which element is a semi conductor the answer is usually Silicon or Germanium. (Memorize that). Then some more random question, which compound its commonly used as an etchant, (HF, hydrofluoric acid). Just take practice tests and memorize those random questions, they ought to show up on the real thing, I know it did for mine.</p>
<p>Like dragooner4 said, it’s really just memorization that helps you out with those questions. I took 2 practice tests (from the official subject test study guide and another I got from a friend) prior to the test and was ready.</p>
<p>Try Barrons Chemistry book,i hadnt done Chemistry for almost 6 months but i got a 750.i read a week before the test.Best of luck!</p>
<p>Questions like that you just have to know or read from the clues. Sometimes they give you “it does something something to the atmosphere” and only one of the choices is a gas, then that’s probably it. Other than that you just have to kinda have to take lots of practice tests and make sure you don’t make stupid mistakes on the exam.</p>
<p>I would get the Kaplan book for chem and go online and google some random chem facts. I got 700s on my practice and got an 800 on the real thing by doing this.</p>
<p>both the questions r actually not random…</p>
<p>Galvanization is taught along with other methods of rust prevention…it’s quite common…</p>
<p>as for semiconductors…it’s a property of metalloids…and that too is mentioned almost everywhere…</p>
<p>good luck but 720 isn’t that bad!!!</p>
<p>Thanks for all your help!</p>
<p>Have you actually read the textbook for your AP Chem class? It should have that stuff in there. Review books don’t have everything.</p>
