When creating a course, you can choose its type.
Calendar Course: each lesson starts at a date specified by the instructor. Mandatory time between lessons is 30 minutes. The course has a start date and a completion date. The students can access the course upon completion.
Regular (Common) Course: no start date and completion date are set for lessons and assignments. The students can start the course at any time and take it for as long as they want.
No Course (Product): creating and configuring a course card is available. The instructor can embed the card in their website or send a direct link to the card to the student. Suitable for instructors who already have a course or a product on another platform (or a file for download) and need to accept payments or take a record of students.
