Unfortunately there are no practice exams offered by PMI, but I do believe that some ATPs have created their own practice question banks.
DASM is effectively similar to the CAPM exam in that 100% of the content relates to DA foundational content which you'd find in Choose Your WoW and in the course materials. As such, I wouldn't be too worried about the level of difficulty of the questions if you've studied well.
Once you get to DASSM, DAVSC and DAC, things get progressively tougher :-)

Hello Kerrianne, I do not know if you are still looking for practice exams.
You might try looking at UDEMY. There are a few 'courses' that aren't courses but contain in fact between 4-6 practice exams. You'll find some from ATPs there too for DASM and DASSM. Otherwise you can do a google search.
