Coursera hosts several Scrum and Agile courses from university and industry partners, usually bundled into its monthly subscription. These are solid for building general Agile literacy, but most aren't built specifically around the Scrum Guide terminology and nuance that PSM I questions test closely.
Because Coursera's catalog is assembled from many partners, alignment with the exact PSM I exam content varies by course. It's worth checking a course's syllabus against the Scrum Guide's roles, events, and artifacts before relying on it as your main prep.
The core gap is measurement: Coursera's quizzes are scoped to whichever course they're attached to, not the specific wording and edge cases the PSM I exam is known for. Edureify's Readiness Score is scored against the Scrum Guide directly and continuously, so you know exactly where your gaps are.
