Hi everyone,
I thought I will share my success story. I have just passed the PSM I exam (spent approximately 30 minutes on questions) on my first try (79/80!) and thinking about going ahead with PSPO.
Earlier this year in May I passed PMI-ACP exam, so Scrum was not new to me. I had to concentrate on details though that PMI-ACP was not covering.
1.) I read Scrum Guide twice + tried the open assessment and had 65%
2.) I looked at incorrect answers and worked to understand why they were incorrect
