Query: Hard Questions but Quite Helpful

Most of the other reviews are right on in that the questions on the three practice tests are very difficult relative to the real thing. Try not to get discouraged with low scores on the Kaplan tests, your actual score will be much higher. I think the best strategy is, as one reviewer mentioned, to begin with the Kaplan prep and take a couple of the ETS tests right before the real test.
