Hey I definitely wanna add that the crack the DAT is a GREAT way to study for the PAT. I only did 3 of the 10 tests from the ace edition and I scored 21 on PAT. I'm certain if I did more it'd be higher, but I wanted to focus on the sciences. Also - actual PAT is way harder than most prep tools (the angles were crazy hard). This resource actually is a little harder than other resources, so that should prep you well. If you wanted to take a test a day, it could take 10 days to become pretty proficient...
