There are 3 kinds of quizzes:

1. 2 true/false, 3 multiple choice.  (12C2)(14C3) =  (66)(364) = 24024 
2. 1 true/false, 4 multiple choice.  (12C1)(14C4) = (12)(1001) = 12012
3. 0 true/false, 5 multiple choice.  (12C0)(14C5) =  (1)(2002) =  2002
----------------------------------------------------------------------    
                                                         Total = 38038
