Self-study for SAT II's?

<p>I need to complete two SAT II's.
I'm taking Math II in October, but I need one more. I answered some practice questions on several different subject tests, and did OK in World History (took classes in 9th and 10th grade), but lots of content wasn't covered. Is it possible to self-study or study with a tutor before October and cover the majority of the content, so I can score 700+ for World History?
If not, are there any other SAT II's I can self study for before next October?
Thanks</p>
