Okay so I've been lurking here for a while and finally made an account because I feel like I owe this community something after all the posts that helped me. I failed the CLI certification in January and again in March — both times hovering around 68% when you need 75% to pass. I was devastated, honestly. I work full-time in supply chain and was only squeezing in maybe 45 minutes of studying a night.
What changed for me was actually switching up my approach entirely. I stopped re-reading the textbook and started doing CLI practice test after practice test, timing myself strictly. I also found a solid CLI study guide that organized the material by domain weight instead of just chapter order, which made a huge difference in how I prioritized my time.
Third attempt last week — 81%. I'm still kind of in shock. Happy to share what resources I used and some exam tips that I think genuinely moved the needle for me. Anyone else here prepping for their first or retry attempt?
