How to Reuse Your Course Content with "Copying Course Content Tool"?

Go to the course that you want to copy content from (source course) and then go to control panel, select "course copy" under course options. Then you select "Copy Course Materials into an Existing Course". On the next screen type in the destination course id (or you can browse to find it, it is in the format of xxx-xxxx-xxx-xx e.g. 05S-MATH-101-01). When you select course materials to copy, don't select all, only select the content that you want to copy. Once when you submit it, you will get a note saying that your course copy is submitted and queued and you will be notified by email when the copy is complete. If you have large amount of content to be copied or if many "course copy" requests are queued, it may take quite some time to complete.

The copy doesn't override so you may end up having duplicate buttons after your copy in your destination course. You can clean them up through Customizing Blackboard Menus.
