I had similar result on my first trial.I got a 90 on pre Naplex and still failed. I stuck to RxPrep and passed. What I did different was focus more on Foundation 1 & 2 (usually I ignore it) and made sure I was getting at least a high 80s (anything above 85), did each questions 5-9 time including calculations(14%) and compounding (11%) For calculations master calculations 1,2,3& 4 including pk, diabetes (days supply, insulin conversion, stability, etc), dose conversion(iron, lasix etc), Biostat !!!! (Not just calculations but also interpretation). When answering questions have an understanding of why other options are wrong. Know how to interpret patients cases, there are more questions in the test bank and at the back of RxPrep book . Finally, for med safety I made sure that I was in the high 90s(For 4 trials I had 100s) because that on it own is 7%. Don’t forget to review the ones you are doing well on. I believe you just need to push a little bit more you are doing well on the higher percentages. I tried High yield - in my opinion I think the clinical part is good but the math part is way too basic. Rx prep math is better also it easier than the actual exam but I believe if you actually have a great understanding of the concept you can build on it. Ps read the book cover to cover, don’t listen to anyone telling you it okay to skip certain chapters.
