The Professional Scrum Master level I and level II should be combined into level I for the following competencies:
- Empiricism, Scrum Values, Roles, Events, Artifacts, Done.
- Self-Organizing Teams, Facilitation, Leadership Styles, Coaching and Mentoring.
- Product Backlog Management, Stakeholders & Customers.
- Managing Technical Risk.
- Organizational Design & Culture.
It will be good to prepare for one exam rather than two exams.
