I used pronto pass also. The big stack of calculations more than prepares you for any math they throw at you. I personally didn't like the AphA review book (way to clinical). I highly suggest a review class. I took the pre-naplex (on the nabp site) and got the same score on the actual Naplex. Besides, it's nice to use the format they use on the actual test. Good luck and relax it's not going to be as bad as you think.
