First attempt I scored a 71%, needed 75% to pass, so I went back and completely overhauled my study plan. The practical section on key systems and lock mechanisms is no joke — I'd underestimated how deep they go on warded, wafer, and disc detainer locks specifically.
Second time around I spent about 9 weeks, roughly 2 hours a day after work. I focused heavily on the ALOA study materials and went through every practice scenario I could find. The business management questions caught me off guard the first time, but they're actually 20-25% of the exam so you can't treat them as optional.
The safe and vault work section is worth serious prep time — I'd give it at least 30% of your total study hours. Flashcards for lock terminology helped me retain definitions without grinding through PDFs repeatedly. Final score was 81%, which gave me a comfortable margin in the end.
Nine weeks at 2 hours a day sounds about right. I did 10 weeks but only 90 minutes most days and still felt underprepared going in. The practical components are where you either know it or you don't — no last-minute cramming saves you there.
That business management section got me on my first try too. A lot of people treat the CML like a pure technical exam and then get blindsided by the pricing and liability questions. Good call flagging that early.
Congrats on the 81%. I passed with a 78% last spring and honestly felt like I'd barely scraped through. Make sure you're solid on masterkey systems before test day — those questions add up fast.
Did you use any specific ALOA prep materials or just the general study guide? I'm 6 weeks out and the disc detainer section is killing me. Any resource that actually clicked for you?
Honestly same boat here, I work full time and have two kids so studying in big blocks just wasn't happening. What actually clicked for me was doing 20-30 minutes every morning before anyone else woke up, plus a quick session on my lunch break maybe 3-4 days a week. I leaned hard on practice tests to figure out where my gaps were — the cml tools equipment operation section tripped me up way more than I expected, and drilling that specifically made a real difference on my second attempt.
The practical stuff on lock mechanisms I didn't give enough credit the first time. It's not just memorizing terminology — they want you to actually understand how the systems work together. Once I stopped treating it like a vocab test and started thinking through the mechanics it got a lot easier. If you're fitting this in around a busy schedule, consistency beats marathon sessions every time.
Just hit an 82% on my last practice run so I'm feeling way more confident this time around. Been drilling the cml tools equipment operation section pretty hard because honestly that's where I lost the most points before — it's one of those areas where you think you know it until you're actually in the test and realize you didn't know it as well as you thought.
Planning to sit the real thing in about three weeks. If you're in the same boat as the OP after a first attempt, don't rush it — that extra few weeks of focused practice made a huge difference for me.
