Tuning up your browser before accessing UMD COB course(s) can help you diagnose technical difficulties. The table below displays the status of all the components required to view all the activities and links in your course.

If the tune-up detects that a required component is already optimized, you will see Passed under the Status column. However, if you are missing a required component, click the Get It! link under the Status column. We also recommend that you optimize your browser and any pop-up blocker settings by clicking the Check link.

If you need further assistance, please open a ticket.
