The progress bars on the course learning page and Dashboard show different information.
On the course learning page, you will see your progress within the module you are on.
Your Dashboard shows your progress on your overall course.
Some courses have two or more modules, so the progress on the course learning page will be different to the progress in your Dashboard.
For example, if you study a course with two modules and you are on the 2nd topic of the 1st module, your Module Progress will be 20%:
When you look at the overall course progress in the Dashboard, you will see that it is only 9% complete. This is because it is reflecting the progress of the course as a whole, not the progress of each module.
We hope this has addressed your concern.
