Okay so I've been sitting on this post for a while because honestly I was embarrassed to admit I failed the ACMT twice before finally passing last month. First attempt I went in way too confident — I've been doing Apple repairs for three years and thought hands-on experience would carry me. Spoiler: it does not. The second time I studied but I was using random YouTube videos and a forum post from 2019. Same result.
What actually changed everything for me was being way more systematic about it. I found a solid ACMT practice test that matched the real exam structure, and I started treating it like a daily thing — 20-30 questions every morning before work for about six weeks. The ACMT practice test I used had really good explanations for wrong answers, which is honestly where most of the learning happens.
The sections that tripped me up most were Apple Configurator workflows and the component-level diagnostic questions — not just "what tool do you use" but WHY you sequence steps the way you do. Anyone else find those brutal? Happy to share more of what worked if people are interested.
