Initially, I didn't believe in PNN as you may read my other comments in topics mentioning about PNN. HOWEVER, recently I talked to a person (here) who failed Naplex 2 times and wondered if he should try PNN (he used Rxprep last 2 attempts). After the discussion, he bought PNN. He told me the lectures and material are very helpful. They are presented in a way that's easier to understand, remember, and stick to your head.
If you failed two attempts using Rxprep already, I would recommend to try other source such as PNN.
