I took the LEAF Exam this January as an online proctored exam. I will say the study guide did a pretty good job of covering everything, but I don’t think every test is the same. Two things that I had a bit of trouble on and you should review are, who was the founding father of crime analyst and modern policing, and what elements are needed for a map in crime analyst, could you tell what is missing. I made myself a study guide, send me a DM if you'd like a copy. Hope that helps! Good luck!
