took cpje 7/20, received my green letter today (58 days later....)
My experience with naplex/cpje: My school had a deal with PassNAPLEXnow so I started using that but ended up paying for the full RxPrep package to replace it. PNP was so unorganized, I didn't like the format of the videos, and my classmates and I found several mistakes in the material itself (ex. guidelines not updated). I also found it impossible to pass any of the quizzes for PNP and it was making me doubt myself. For a month, I went in order of RxPrep book, and went over important chapters again 2-3 times after that. Started doing the SDN practice calculation questions, but it's overkill and way harder than the actual questions. Took the prenaplex twice (which definitely helped boost my confidence vs the RxPrep exams). Took the naplex first then cpje 2 weeks after that. I gave myself like 4-5 days to rest/recharge, then read the weissman law book twice and skimmed over the important chapters in RxPrep again, this time focusing on things cpje tends to focus on (like compatibilities and special expirations/bud, sterile compounding, pharmacy operations).
hope that can be useful to someone!
