So I just got my results back yesterday and I finally passed the DWO certification on my second try. Honestly feeling a mix of relief and frustration because I really thought I had it the first time around. I scored a 71 on attempt one, which was two points below passing. Devastating. I'd spent maybe three weeks studying but clearly not the right way.
What changed the second time was finding a solid DWO practice test that actually matched the format of the real thing. I was using a generic study guide before and it just didn't have the depth I needed on the technical sections — especially the operational procedures and safety protocols. I put in about 45 minutes a day for six weeks straight, focused on my weak areas, and came away with an 84. Night and day difference.
For anyone else prepping right now, my biggest exam tips would be: don't just read the material passively, quiz yourself constantly, and pay close attention to scenario-based questions because they made up probably a third of what I saw. Happy to answer any questions about the process if it helps.
