In many Blackboard tests, a timer is set by the instructor. Here is some additional information regarding the timer used in Blackboard.
This is what it looks like:
The timer resides at the top of your browser window as you complete the test. Even if you scroll down the test, the timer remains at the top of the browser window. You can minimize the timer, but it is not suggested. Here is what that looks like:
The timer also allows you to expand the Question Completion Status so you can see your progress on questions. All questions that have been submitted and saved are greyed-out with a little save icon. Note: You can navigate directly to questions by clicking on these question icons (if permitted by the instructor).
Always be aware of the time you have on your test.
