I may be available before class on some days. If you need to see me but cannot do so during these times, please contact me and I'll try to work something out.
  • Three exams, 30% each (the final exam is not cumulative)
    Make-up exams will only be given with a written medical excuse.
  • Attendance: 10%
  • Homework: not graded, but absolutely essential for success.
  • Read the relevant textbook sections in advance of the lecture. When reading, have pencil, paper, calculator, ruler and graph paper handy and work out the examples and 'Matched Problems' as you read.
    The lecture material follows the textbook material very closely. If you don't fully understand something while reading the textbook before class, it will likely become clearer during the lecture.
  • Attempt at least some of the homework problems in advance of the lecture.
  • Do not miss class! One class during Winterim is equivalent to one week during an ordinary semester. Turn your brain on, be active and participate.
  • Do all homework problems.
  • Do at least some of the unassigned problems.
  • Come to see me if you feel you don't understand something.
STUDENTS WITH DISABILITIES Please feel free to contact me early in the semester for any help or accommodations which you may need.
