Finally passed my supply chain logistics certification after two attempts — here's what worked

So I just got my results back this morning and I finally passed. Honestly I cried a little. I work in warehouse operations for a mid-size distributor and my company started requiring this certification for anyone moving into a logistics coordinator role. First attempt I scored a 71 and needed a 75 to pass, which was gutting because I felt pretty confident walking out of the test center.

For round two I completely changed my approach. I spent about 6 weeks this time instead of three, and the biggest difference was actually drilling with a supply chain logistics practice test every single day for the last two weeks. Not just reading — actually timing myself and reviewing every wrong answer. The demand planning and inventory optimization sections killed me the first time, so I made sure I understood EOQ formulas and safety stock calculations cold.

Anyone else studying for this right now? Happy to share what resources I used or which topics to prioritize. The exam tips that helped me most were honestly about pacing — you get more time than you think but it's easy to panic on the quantitative questions.
