Just got my results this morning and I'm officially a Certified Maintenance and Reliability Technician. Took me two attempts, so I figured I'd share what made the difference the second time around since I spent weeks searching for decent advice and couldn't find much.
First attempt I went in after just reading the BoK document and some random notes I found online. Scored a 68, needed a 70. Brutal. For round two I got serious — built a 6-week study plan, focused heavily on maintenance planning, lubrication fundamentals, and machinery troubleshooting since those are weighted heavily. The thing that actually moved the needle was doing a proper CMRT practice test repeatedly under timed conditions. Also grabbed a solid study guide that broke down each domain instead of just listing topics.
Anyone else preparing right now? Happy to answer questions about specific topic areas or what the testing experience is like. The exam tips I wish I'd had earlier were mostly about time management — some questions are wordy and eat your clock fast.
