Failed my VT MPJE

So I failed my VT MPJE. I used prontopass, as well as rxexam. I felt like I had both mastered. During the exam I felt great, and the questions were pretty straight forward, or so I thought. I did very poorly, scoring a 69%. Any advice how to study better for this? I am very upset with myself. I felt like the questions I did not know were heavy retail type questions, when I only have hospital experience.

Guess I wait my 30 days. Thanks in advance for any advice

Edit:
Would like to mention I...
