Getting certified as product owner or scrum master with Scrum.org on your first attempt.

I recently got re-certified. For work purposes. The required  Scrum documents are not wordy, but content rich. You need to know them well. Scrum Master 1 and Product Owner 1 overlap, so studying material is about 75% similar.

Review the learning paths at scrum.org

and https://www.scrum.org/professional-scrum-product-owner-i-certification

1)Read and learn

• the manifesto.

Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan

• Scrum Guide, 18 pages https://www.scrumguides.org/index.html
• EBM Evidence Based Management Guide  11 pages https://www.scrum.org/index.php/resources/evidence-based-management
• Optional – videos and recommended books https://www.scrum.org/index.php/resources/webcasts

2)Write out flash-cards based on the material. I prefer by hand, uses muscle memory. Glossary, manifesto, etc. Plan to make hundreds of cards.

3)Take practice tests at scrum.org till You score 100%

Review other reports on passing the exam.

Last, remember that only individuals and organizations that You do not want to work for care about your certifications and not what You can deliver. So in the worst case scenario, use that pretty piece of paper to get the first step to find a position where working software beats documentation, including certification.
