Note that machine problem 5, where an extra week was given and the total score was doubled, was graded as two machine problems, MP5 (issues of style and input format) and MP6 (issues of data structure).

Total Scores

Mean =   30.31
Median = 32.1

As usual, midterm scores can only be considered to be advisory and are no guarantee of any final score.

Note that the three low scores are for people who stopped attending after the first two weeks of class; they really should not be included in the distribution.
