Each course page uses a combination of elements you will need to view, answer and interact with. Some of these may include Videos, Multiple Choice Questions, Carousel of Images, etc. In order to unlock the NEXT button and proceed to the next page, you will need to interact with the course page elements.
The most common element users gloss over are the videos. Videos will need to be viewed from start to finish without skipping.
Multiple choice questions or other question-type elements usually come after a video or in some cases by the end of the course. These elements will need to be answered correctly.
Other Interactive elements will need to be viewed also in order to proceed.
