Udemy's appeal for AZ-900 prep is the price — self-paced video courses, often taught by well-known independent instructors, covering Azure's core services, cloud concepts, and pricing/governance basics at a fraction of official training rates. Several Udemy AZ-900 courses are genuinely excellent and widely recommended by past candidates.
The gap is the same one that shows up across any self-paced marketplace: a video course can't tell you specifically which of Azure's core services, cloud concepts, and pricing/governance basics you're actually weak in. You finish the course knowing you watched everything, not knowing whether you've retained enough to pass.
Edureify's Diagnostic maps your understanding across Azure's core services, cloud concepts, and pricing/governance basics on day one, and the Readiness Score keeps updating as you practice — so instead of a vague sense of completion, you get a specific, evolving answer.
