When you enroll in a new Class, one of the tasks you are required to accomplish in order to complete its curriculum is to take a test to validate your comprehension of the topic area. In order to do so, simply click the Load Test control in the Test section on that Class' page.
The succeeding page will provide information about the Test, including the number of questions on the Test, how long you have to complete it, the minimum score required to pass and more. To begin, simply select Start Test.
Your Test score will be tracked and displayed in the top right corner of the Test section. If you achieve a passing score, this will represent 100% completion of the Test task and this will roll up to the overall progress at the top left of the page for that Class. This progress will also be displayed in your My Courses, My Classes, My Tasks and overall My Company views of your Dashboard.
