<p>I bought Kaplan's 09-10 books for the Physics and Math II SAT Subject Tests but I decided to take the tests this October instead of last June so I'm wondering if the tests have changed much or if I can still study from the books that I have. I'm aiming for 800s so I would like to know if even a single topic has been added or removed from the test or if any other changes have been made.</p>
<p>It’s fine, nothing has changed much in one year. By the way, I would suggest Barrons if you really want those 800s.</p>
