I passed the PSPO I, Professional Scrum Product Owner exam and wanted to share my preparation techniques with others. Taking the test is not difficult if you know the material well. That means reading resources like the official Scrum handbook until you fully know and understand all of the information in it.
Tests to prepare: https://www.scrum.org/open-assessments take the PSPO and Scrum Open Assessment until you get 100% on them quickly. The test is somewhat randomized and very similar questions do appear on the exam.
Additional Practice Exam
Another good practice test is available online and has two modes, practice and real mode. Practice mode will explain the correct answer and why it’s the right answer. Make sure to take that exam a few times. https://mlapshin.com/index.php/scrum-quizzes/po-learning-mode/
Official Scrum Resources
Here are additional scrum.org resources by their focus area. Make sure to read these resources in order to get a better idea in how to pass the exam. Each of these topics will be covered on the scrum product owner exam. Make sure you reach the various articles from each topic.
