I felt that the 2007 sample was fairly accurate on the Total Science, Reading, and Math sections. However, I felt that the PAT was significantly more difficult on the real DAT. Apertures, top-front-side view, and hole punching were much harder than the 2007. Not to say I didn't do well and it wasn't possible to do well but the 2007 practice just didn't simulate the experience. I would suggest reviewing DAT Achiever for the PAT because they better prepare you for it.
