What is a Lesson?
A lesson is a single video file where the tutor focuses on a specific topic or subject matter. Lessons are the building blocks of courses. For example, “How to answer multiple-choice questions in IELTS Reading” can be the title of a lesson.
There is no upper time limit to a lesson. However, we suggest that you keep the duration of a lesson to 30 minutes or less. If you need to cover a large area in a lesson, consider creating several lessons and adding them to a course.
NOTE: You can use a lesson in several courses.
If two or more lessons cover the same topic and come as a bundle, you can use the same title for all of them and add “Part 1”, “Part 2”, … to the end of the titles.
What is a course?
A course is a series of lessons that come in a certain order and prepare the user to master a specific skill. For example, “Introduction to IELTS Reading” can be a course title.
A course should include at least 3 lessons to become published. It is important that the order of lessons in a course is correct. This means that lesson #2 in a course should cover what users will have to learn after watching lesson #1, and so on. You can set the order of the lessons inside a course by drag-and-drop.
