Registered for the MDRAO exam next month and trying to prioritize since I only have about 3 weeks left. I work in a sterile processing department already but the exam covers a lot of regulatory and standards content I haven't touched since training.
My manager said decontamination and sterilization processes are the heavy hitters but I've also heard quality systems and documentation are tested heavily. Can anyone confirm?
Also wondering how strict the question wording is — like, does it test exact CSA standard numbers or more conceptual understanding?
Documentation and traceability questions show up more than people expect. Know the required elements for a device history record and what biological indicator records need to include.
They don't usually ask you to recite specific CSA standard numbers but you need to understand what each standard governs. The MDRAO practice test helped me figure out which standards were actually tested vs just background knowledge.
Quality systems questions are conceptual — root cause analysis, corrective action, nonconformance reporting. If you've done any ISO 13485 training at work that knowledge carries over directly.
Decontamination is definitely the biggest section — expect questions on temperature thresholds, chemical concentrations, and PPE requirements for decon zone. Know the difference between cleaning, disinfection, and sterilization cold.
Honestly, decontamination and sterilization are definitely the heavy hitters, but don't sleep on infection prevention -- it's more detail-heavy than you'd expect and it's where a lot of people lose points because they know the right answer but can't explain why the others are wrong. I found the mdrao infection prevention and control 3 practice test really useful for that, specifically because it forced me to think through the logic behind each distractor, not just pattern-match to something I'd memorized.
Three weeks is enough if you're strategic. When you miss a question, don't just move on -- actually sit with why that wrong answer seemed plausible and what principle it was testing. That clicked for me around week two and it changed how I studied everything else, including the regulatory stuff your manager mentioned.
