passed Foundation today. thought I missed 30% of questions where it asked things like support cases which we don't use (aka Zen Desk is better). I thought I failed and didn't review any questions and took 30 min to complete. Maybe they weight real questions like segmentation more. Very weird test. I only took the NS practice once and passed but I have been customizing a lot for the past several months and knew several things from experience. I think in general you can pass 50% if you are active in implementing your company from ground zero, 20% from reducing choices, and maybe another 10% from lucky guesses. I am really wondering if passing score is 50% or 80%. No way to know.
