I do want to point out the view of my friend who had just taken the August 22nd test.
He describes the AAMC FL as easier than the real MCAT, and that the real MCAT was similar in difficulty to the Kaplan practice tests that he had taken. Of course, control for the fact that despite Kaplan's rigorous content-review intensive questions, my friend has no problem with those questions. So it would be safe to say that the analytical requirements are similar to Kaplan's tests (not necessarily the content review necessities.) He is a pretty smart guy, and scored 95% overall on the AAMC full length, and has gotten consistent 510+ on Kaplan and TPR practice tests leading up to the exam.
Though he says that he wishes he spent more time studying/practicing for CARS.
