How much time to study is needed?

<p>How long do you think I will need to prepare for the sat II exam? (mainly world history, but any really) THANKS!</p>

<p>It depends on how well you know the subject. Did you take a particularly challenging class in that subject? If so, you probably won't need more than a brief review. You should take a practice test, and, based on that score, create a study plan- if the score is low, plan to spend more time studying and vice versa.</p>
