CHANGES to the 1st day handout,
due to the power blackout during the 2nd midterm exam
and the decision to turn this exam into a take-home exam:

1) The 2nd midterm exam will contribute 20%
   to the class grade, instead of 30%.

2) The final exam will contribute 40%
   to the class grade, instead of 30%.
   The final will be a 3 hour exam, Thu Dec 13, 2-5pm.
