Thanks, Henry. You make a good point about courses and assignments. Let's
assume that the TAssignment objects will be created in the TCourse object.
TCourse is the main class, and a Course object should be the only one called
by the user interface.
To help you understand the rubric concept, think about times you've watched
sporting events where someone gives a performance and other people judge the
performance. The judges have a list of required moves the performers are
supposed to do ("performance criteria" or "expectations") and they write
down judgments on how the performers did on each criteria. They might be
required, by others, to note anything from a grade from 1 to 10 on each
criteria all the way to something as simple as "yes s/he performed the move"
or "no s/he didn't perform the move." For our purposes, a rubric is nothing
more than an analogous list of expectations for what a student is to
accomplish on an assignment and then judgments about how the student did on
each individual expectation. (For an example, see

Thanks again for your help as I continue struggling through the land of
Objectville :-)
