I passed PSM 1 with 74/80 92.5% and I didn't expect it to be that tricky.
I been using scrum for more than 2 Years, 1 scrum team with 6 Developers and a product owner.
Since last week I read the scrum guide twice and a couple of questions came from the guide. Most of my Exam Questions were based on real day to day scrum experiences. At one point I felt like I started the wrong exam, scenario after scenario. Before the exam I did the open assessments scoring 100% 3 times but the questions were all the similar so i stopped and went for the real scrum test.
