Regardless of teacher preference, providing students with various strategies allows them to experience the diversity in problem
A: Exemplary Work
A = 4.00; A- = 3.75

All of the previous, in addition to the following:
B+ = 3.50; B = 3.00;
B- = 2.75
All of the previous, in addition to the following:
C: Minimal Work

C+ = 2.50; C = 2.00;
C- = 1.75
F: Work Submitted but Unacceptable
F = 1.00
