Today I have cleared PSK I with 95% on my first attempt. Here are my review points,

1.This course is very useful for the actual assessment. Also, Q&A discussions made me feel like a live session.Guaranteed quick response from the instructor.

2. Practice assessments are more related to actual assessment and you can expect questions similar to this in the actual assessment.

3.The practice questions are up to date with latest kanban and Scrum guide

4. My suggestion is to go for this training and read Scrum and Kanban guide thoroughly and not to go for other open materials/assessments because most of them are not up to date and will confuse more.

All the best.
