Our online courses are like real-life courses. You receive one lesson at a time. Lessons are programmed to appear at regular intervals, depending on the course. When you sign up, you have access to the first lesson only. The other lessons become available one by one. So if a course has eight lessons, and you receive one lesson a week, you will be able to see two lessons the second week, three lessons the third week, and so forth until the eighth week, when all eight lessons are accessible.
If you’re certain a lesson should be available (for example, it’s week 3 of the course, but Lesson 3 isn’t opening), your system may be loading an old version of the page. Please try clearing your cache and removing your cookies and reboot your computer to see if the lesson becomes available (this will require you to login again).
