Adult Psychiatric Nurse Practitioners

Hi,
I just joined allnurses.com. I took the Psychiatric Adult NP exam with ANCC... didn't pass the first time. I took the Barkleys review course and it didn't help at all! I reviewed the course religiously and looked over it 3 times and guess what? 90% of the exam was on something totally different nothing related to what Barkley reviewed...very dissapointed! I also took the ANCC review course and it didn't help much either. So my question to my colleagues out there, is there any review out there that really gives realistic test question examples that can help one pass the boards? Your help is greatly appreciated.
