The QR section is sort of a wild card. You should be ready for everything. I think the BootCamp QR and Math Destroyer are great tools to practice but it also depends how good you are. I was not that great at QR but got a version that wasn't bad so I scored a 19. The best tool for PAT is DAT BootCamp. The generators are awesome, and the tests are a little harder but it helps prep you a lot for the real thing. My highest score on BC PAT was a 20 and I got a 24 on the real thing; I couldn't believe how easy it was compared to BootCamp.
