I want to tell everyone that the scrum.org exam is very standardized and respectful, and is currently the best global exam, I think so.
I hate the paper test of PMI Global only in China! Although I had no choice but to take the PMI exam. I still hate it.
The scrum.org certifications and exams are all:
1. Based on the understanding of "Scrumguide";
2. Based on your actual scrum implementation experience accumulation;
3. Based on whether you solve the problem and follow the "Scrumguide";
