You can check your completion status and points (if in use) anytime under the "Performance" button on the main page of your course.
On a mobile screen, you will see just the icon on the top right on the Path.
Your grade card will look something like this.
The check marks beside each step show you how much of the course you have completed.
If your course uses points, you can see what score you achieved out of the total possible points so far in the course and you can review your score on each graded step.
Select a step name to go to that step.
