A standard Udemy course is video-based. Courses must have at least 30 minutes of video content and at least 5 lectures or learning modules. Additional teaching tools (like assignments, quizzes, and coding exercises, etc) can be added to create a rich learning experience for students.
In order to ensure that students have great learning experiences, we also have a Quality Review Process that every course goes through. For more information on this please click here.
