You can access your previous attempts at a specific test so you can keep an eye on your progress. You can also analyse these tests to see if you are continually making the same mistakes or to see if you are retaining the knowledge.
On the first course page there is a menu which allows you to access your grades.
Clicking on this will give you a list of all of your scores in that particular course, ordered by topic.
This gives you another way of checking your progress.
The grades are listed in order of topics so you can clearly see your strengths and weaknesses in different areas
On the homepage each of the course boxes has a radial scale showing your overall progress in that course.
I hope this helps you to use this site successfully.
