I failed the RMA at 68% and just got my passing score back — 78% on the retake. Figured I'd write up what was different in case it helps anyone else in the same spot. The first time around I studied for about 3 weeks, maybe 45 minutes a day, and relied mostly on flashcards. That was clearly not enough for the clinical sections.
For the retake I went 6 weeks at 90 minutes daily and completely restructured my approach. I stopped using flashcards as my primary tool and switched to timed practice exams after the first 2 weeks of content review. The diagnostic labs and clinical procedures sections were my weak spots — specifically normal reference ranges and the step sequences for common procedures. Those don't stick from reading, they stick from repetition under time pressure.
One thing that helped early in my prep was actually researching rma meaning medical because I was confusing the credential with other assistant designations and wasn't sure which scope of practice questions to focus on. Once I understood the ARMA framework the content categories made a lot more sense.
The administrative sections — billing, coding basics, HIPAA, scheduling — are a bigger portion of the exam than I expected. I'd say 35-40% of the questions on my version touched administrative material. Don't let the clinical side crowd that out entirely.
Lab reference ranges are brutal if you try to memorize them cold. I made a single cheat sheet with the ranges that appear most often and drilled it every morning for 4 weeks. That alone probably moved my score 5-6 points.
Six weeks at 90 minutes sounds like the right volume. I see people rush it into 3 weeks and they're just not retaining the procedural detail. That kind of material needs more time to consolidate.
The administrative section surprised me too. I was a clinical MA for 2 years and thought I'd do fine, but the billing and insurance questions were things I barely touched at work. Spend specific time on those even if your background is entirely clinical.
The second-attempt jump from 68% to 78% is actually pretty common — most people who fail the first time know the content, they just don't know the exam format well enough. Doing full timed practice tests is the fix for almost everyone.
I passed first attempt with 74% and the timed practice tests were the main thing I credit.
