So I've been lurking here for a while and figured it was time to give back since this community helped me so much. I work in operations management for a mid-size distribution company and my director basically told me getting the OMST certified would fast-track my promotion review. No pressure, right? First attempt I scored a 68 — passing is 75 — so I was gutted. I'd only studied for about three weeks and honestly winged a lot of the supply chain optimization sections.
Second time around I went way more structured. I grabbed a solid OMST study guide that broke down each domain (operations strategy, process improvement, quality management) and spent about six weeks this time, roughly an hour a night. The biggest game-changer was using an OMST practice test to simulate real exam conditions — timed, no notes, the whole thing. My weak spot was lean methodology questions, so I drilled those specifically.
Scored an 82 on the second attempt. If you're just starting out, don't underestimate the inventory management section — it's heavier than the official outline suggests. Happy to answer questions about what resources I used or how I structured my study schedule.
