Hey, I'm an NV P1 too, but I haven't had to reassess yet. I definitely agree with you that the Roseman curriculum is tough. A two week block is probably the equivalent of a 5 week undergraduate biochem midterm in terms of difficulty. However, I'm not sure that people are really going to find a significantly easier program out there. Plus, the 90% is somewhat relative to the difficulty of the questions (e.g. the PCalc exam requires 90% but was way easier than a normal block exam). Right? That may just be my perspective anyway.
I did, however, notice that the non-BS degree pharm techs were struggling more than those who had taken biochem, molecular bio, cell biology, etc. Does that describe your situation?
