I passed the naplex with a score of 120 Thank God and I'm waiting for my CPJE scores...when i first started studying for the Naplex i was using the APHA but there was too much details in it and i was kinda lost so after a while i decided to get prontopass and i started studying from it but after a while i realized that it is far too detailed also so my last resort was RXprep and i think thats the best out of all of them, it's straight to the point, easy to study and not complicated at all so i ended up studying from Rxprep the whole book, and the calculation from prontopass i think its a good source for calculation as it covers a lot of areas and i answered the questions at the end of each chapter in APHA and the quickcard summary of porontopass, thats my experience with the naplex, if anyone has questions tell me and good luck with the naplex and i believe its not that difficult and passing naplex is easier than everyone thinks !!!
