Hello,
I’m preparing for the PSM certification for a while which I would like to do based on the 2017 “version”. The Open Assessments from scrum.org; the Scrum Open, Product Owner Open and the Nexus Open have been completed several times with a 100% score. All assessments from https://mlapshin.com (the Scrum Master, Product Owner and Scales Scrum) have been studied and completed as well with a 100% score. All documents provide via scrum.org have been carefully studied and are the basis of the study.
