You really can't compare sections across different tests, they can be quite different. Your overall score on the tests, however, will likely be similar. With AAMC 5 and 6, the scores that you get on these tests will most likely be +/- 1 point what you get on the real thing. This of course, is barring a massive high yield study effort or a one night fling with tequila and crack the night before the test.
