Which to take for December?

<p>Hey everyone, just registered here (been a lurker for a while now).
Anyway, I have a question on what to take for the December SAT 2s -Chemistry or U.S. History.</p>

<p>The only chemistry experience I have is Chem Honors and I took the test in June and got a 660 on it. I'm not taking Chem AP this year so I'm not sure if I'll be ready within a month. I'd appreciate it if I got suggestions + info on what books I should use to prep for either of them.</p>

<p>Thanks =o.</p>
