If there are a limited number of the course level you could use Running Totals for each of the course levels and then use the formula button in the running total form to set the value to count.  It essentially is a true statement.  If value is true then count kind of thing.

 

You could always create manual formulas which takes  three formulas you place at the appropriate place on the report design. For example, the Report Header, Details and Report Footer. You create shared variable and use the the WhilePrinting to set which pass the count is to occur. The report header creates a shared variable then set the value to 0. The details repeats the creation of a shared variable of the same same name, sets the logic for the count and the adds 1 to the shared variable. These first two formulas are suppressed and finally the report footer formula creates a shared variable of the same name as the report header and details, then return the variable which is the count. It works like this

 

Header  x = 0

Details   x  = x + 1

Footer    x

 

Hope this will help, the CR help file offers more complete discussion of the later two choices.
