+Also displayed is are rectangles indicating whether or not each of the gen-ed requirements

+This is then completed for each subsequent semester, until there are no more classes to select.

+What if a user wants to modify their trajectory? They can select to go back to any semester, but
+it will delete their progress thus far for something.
