Advice to pass PSM 1
To be honest my target is to pass PSPO1 certification but before this I wanted to pass PSM1 because in my mind about 70% of questions are the same in PSPO1 and in PSM1. In general my preparation took about 15 days. I've passed PSM1 and my score is 96.3 %
I've used three types of materials:
1 - Of course Scrum Guide. The big plus of this is that you may read this (with big attention) just for 20-25 minutes
2 - http://www.scrumcrazy.com/ScrumCrazy.com+-+Charles+Bradley - very good articles. Thank you Charles
My next target is PSPO1. What will you recommend me? Thanks in advance :)
