I can't fully remember the bootcamp scores but the sciences were all just around 18-20, QR 19, RC 20 and I could not get a score PAT since the the free membership does not give you a full PAT test to work on. QR was pretty representative of the real test and I can confidently say that RC on bootcamp was a lot harder than the DAT (scored a 26). In terms of PAT, if you're consistently getting 20's with bootcamp (one of the more representative practice exams) I would expect 20's on the PAT. I think overall bootcamp is a bit harder than the DAT but thats probably intended to get you ready for test day.
The main study material i used was...
Kaplan Blue Book:
-spent three months reviewing the whole book while making my own sort of study guide/flash cards to go along with the material
Topscore Pro:
-used this for practice exams in the weeks leading up to the DAT
Also found many resources online for extra practice including free bootcamp tests, ADA practice exam and all of the free PAT practice I could get my hands on
