I just passed the CISM exam, and I didn't prepare at all. First I don't really have time to do it, but I was motivated by some forum posts recently and I thought I'd give it a go!
Went with the mindset of: Think like a manager, risk assessment is good, don't overthink questions
I don't know what my score is yet but I passed. The questions weren't really strange, just real world scenarios, play on words, and just basic high level stuff that I've seen over and over in my day to day jobs
Goal: MBA, March 2020
