So I just got my results back yesterday and I actually passed this time. Genuinely shocked because my first attempt was a disaster — I went in thinking my field experience would carry me and scored a 71, which wasn't even close to what I needed. That was back in February. Spent the last three months actually studying properly instead of just winging it.
The biggest difference this time was using a structured IDC practice test routine. I was doing 20-30 questions every morning before work, then reviewing every single wrong answer instead of just moving on. That review step is where the real learning happens, honestly. I also grabbed an IDC study guide that broke down the divemaster leadership sections — those had killed me on attempt one because I underestimated how much theory was involved versus practical skills.
My exam tips for anyone prepping right now: don't skip the rescue protocols section, it shows up more than you'd expect, and give yourself at least 6 weeks of consistent prep time rather than cramming. Happy to answer questions about what resources I used if anyone's in the same boat I was.
