When to study for SAT subject tests?

<p>I plan on taking the Math 2, U.S History, and Physics tests. My school does not end until late May, so I was planning to begin studying after I finish all of my AP exams. I am concerned however, because the latest testing date offered for subject tests is June 2. I don't think that will give me enough time to study. Will testing be offered again in October of 2012? Also, will I be fine taking all of my tests on the same day? Thank you</p>
