Kaplan does a ridiculously poor job in putting together some of their practice tests. Their review notes are awesome, but many of the tests are terribly inaccurate. They will put a whole physics section together that has all very time consuming questions on it, and then another that is 20 times easier. They don't take the time to put together those tests for OAT people, so don't let that 230 bother you. For example, one practice test I aced the reading section, and bombed the physics. On the real test, I did extremely well on the physics, and reading comp was my worst score.
