20 on the Academic Average and Total Science is competitive and a 19 on the Perceptual is pretty good as well. There's a section for: biology, gen chem, organic chem, reading comprehension, math, and perceptual ability. Buy the Kaplan blue book...its a great way to prepare and has a couple practice tests to get you ready (be warned, the Kaplan PAT is quite a bit easier than the real thing). Good luck and PM if you have any other questions.
