<p>Im planning on taking the november test, and I am currently in AP Physics B. last year I took honors physics, which did not include thermodynamics, magnetism, or modern physics.</p>
<p>Ive been preparing with both sparknotes and my princeton review book, and I just took the first princeton review test today. I scored a 640, then a 670 on sparknotes, and a 740 on princeton review. Which is more accurate? Granted I did learn thermodynamics in between the second sparknotes test and the princeton review, but which prep is a more accurate predictor? And do any of you guys have last minute tips for the test, or random facts that might be useful?</p>
