Thanks for pointing out the issue about inaccessibility of the book through Amazon. We are actually looking into alternative distribution methods for future editions - which country are you from? This will help us make some decisions about publishers, etc. Also, we make individual chapters and practice tests from our book available for sale on our website, www.physicsgreprep.com
. If you've already bought the Sterling book, you're probably well-prepared for classical mechanics and E+M, and might only need the more advanced subject reviews.
Would you also consider writing a review of the Sterling book on Amazon? I'm worried that many of the positive reviews do not accurately reflect the mismatch between the level of that book and the level of the Physics GRE, and I'm not allowed to write a review myself because of my status as author of a competing book. I agree with you about the difficulty level of the questions - while ours may run a little hard, theirs are certainly below the level of the test, and in fact the book seems to be based on a non-calculus high school curriculum suitable for the AP Physics test.
