Lessons unlock in order
Each course is a sequence of video and article lessons. A lesson unlocks when the one before it is complete.
- Videos are complete once you have watched 85% of them.
- Articles are complete when you click Mark as read at the bottom.
Progress saves automatically
The player saves your position every 10 seconds. When you come back, the course opens on the first lesson you have not finished, at the point you stopped.
Player controls
- Speed: 0.5x, 1x, 1.25x, 1.5x, 2x.
- Captions are on by default. Turning them off is remembered in that browser.
Going back over a course
You keep access to a course after you are certified. Certified courses show a Review course button on the course card so you can rewatch any lesson.
The exam button is not showing
The exam only unlocks when every lesson in the course is complete. Open the course and look for any lesson without a check mark, usually a video you stopped just short of 85%.
