\label{Course_Problem_Weight}
The ``problem weight'' parameter is used to calculate the points of a
problem.  The default spreadsheet uses the weight as the points.  You
may want to think of a problem's weight in comparison to other
problems.  For example, all problems with a weight of 1 means that
both easy and difficult problems are given the same weight.  If you
choose to customize the spreadsheet, then the problem weight and
points may not equal each other for your course.  The default weight
of all problems and problem parts is 1.
