What SAT prep can I do now?

<p>Hey guys, I am an international student and I started studying for the SAT's about 2 months ago. Well, let me brief you about my situation. I finished the 6 KAPLAN Tests, 4 Princeton Tests that come in the princeton book and 6 BARRON's Tests and 2 BARRON's Test from the math workbook as well. Also, I have finished 6 practice official college board tests. Thus, I have 4 left. However, the main dilemma is that my SAT is in May 1st and with 2 months still left, I have only 4 tests remaining. They will definitely not last the entire 2 months. So, I was thinking to get either the 11 Princeton Review Practice tests book or the Kaplan variant. But will they interfere with the kind of official SAT tests I have taken? Are they fair representations of real SAT's.</p>

<p>I don't want to finish the 4 official SAT practice tests and then have to do the unofficial tests. Therefore, is the pragmatic approach to do unofficial tests or simply not buy any additional books at all and simply redo the official tests? This forum is known for its great and helpful responses and I'm hoping for the same. Thanks.</p>
