APPROXIMATE Letter Grades

The following is a rough guide, and is based on my assessment of how hard the test was. I do NOT promise to use the same scale when computing final course grades. 
SCORE out of 72    APPROXIMATE Letter Grade
  60-72                A- or A
  50-59                B-, B, or B+
  39-49                C-, C, or C+
  30-38                D or D+
Note that there is a lot of room to move up or down after the final exam.
