Here's one way to accomplish that...
Place the video on the timeline.
Split out each course by moving the red cursor to the junction between them and pressing the L key or clicking on the split scissors icon, creating ten clips.
Select (highlight) the first and press <ctrl-C> to Copy it.
Click on the Sequence tab + sign to create a new, blank sequence. 
Press <ctrl-V> to Paste the copied clip into sequence 2. Click the Sequence 1 tab and select clip 2. Copy it. Create a new sequence and Paste.
And so on, until there are ten sequences, each containing a course.
Click the Menu (top-left of the window) | FILE | EXPORT ALL SEQUENCES. The shortcut is <ctrl-shift-X>. Leaving the settings at the defaults is usually fine.
Choose FILE | VIDEO FILE and OK each export. The result will be ten individual files in the PC folder of your choice. By default it's the Videos folder.
