Pray honey, pray. I don't know if you believe in God and the power of prayer. But our God can do it all. He shows us or leads us to something that we have not been doing or something we need to add on to help us succeed that we didn't know we needed. All we have to do is ask Him. Jesus said if you ask of anything in my name, I will do it- John 14:14. But you gotta have faith that what you are asking from God, He can do it.
Now the physical aspect, how are you in math? Are you average or need more help. Math is everything on Naplex. If you don't pass the math section, am sorry but you fail the whole exam. So if I were you, I will do more calculation questions. Do it until you are 100% confident. Make sure you know mEq, mmols and mols, alligation, aliquot, flow rates, percent composition, dilutions, pediatric med calcs like acetaminophen and motrin calculation (the formula for both), density, specific gravity, CrCl, dosing for vanco (actual body weight even if obese), aminoglycosides ( know when to use Act BW, IBW Adj BW). Then for biostats, the usual NNT, NNH, ARR, RR, CUA, CMA, CEA, CBA. Make sure you know everything like the back off your hand. Trust me, really pump up your calculations sections, and that will tip you over into the 75% and above passing grade! Of course you gotta brush up on and know very well our common pharmacy topics; DM, HTN Asthma, dyslipidemia, HF, Anticoag, sterile and nonsterile compounding, ID, Onco, Psych, drug references. And know everything from the other topics just because they bring questions from everywhere else, but don't try to know it all. Just know the basics from the other small topics; refresh your memory for those sections so you are not caught off guard in case a random question pops up. But the reality is that, you won't know everything! So if you don't know a question, make your best educative guess and move on so you can concentrate with more time on the questions you are confident in.
So first pray, and be proactive about it. God will get you there. Work hard on your part, use this strategy, and I know you will pass this time around.
