From what I've read on here, Pre-Naplex is not predictive. Search for "Pre-Naplex" threads on here and you'll see what I mean. I took pre-naplex about 3 weeks ago and got a 74. I haven't let up on the studying though. I take the NAPLEX next week. I thought about it (taking the pre again), but I'm not going to take the pre-naplex again. If I was to get a lower score, I'm sure it would be pretty disturbing being this close to the actual test.
Do you feel pretty confident? What are you using to study? If RxPrep, you doing ok on the quizzes?
