ECS 120 – Theory of Computation – Winter 2012

Announcements

• I graded exams and assigned grades in record time; all done.
  Finals were graded out of 96 (I decided to bump down the last page of questions from 20 to 16 points).
  Median was a somewhat disappointing 44/96, range 9-88.
  Overall median for the class was 51/100.
• Your graded PS8s are outside my door (3009 Kemper).
  Please pick them up Spring term (after that, they’ll be recycled).
• Have a lovely (but short) break. Do good.
