Extra points on final

Final will have 32 instead of 30 questions.
  • All midterms are counted in the score (no dropping of lowest score) unless there are exceptional circumstances.

  • Homework percentage will be calculated relative to 80% of the total possible HW points, HW% = 100 * (HW points)/(0.8 * possible HW points). HW score will be capped at 100%. This provides 20% buffer for technical problems. No extensions will be given for HW without exceptional circumstances. Students are responsible for finding a site from which they can enter their answers. "The net was down when I tried to enter problems from Ohio" or "I couldn't get LON-CAPA to work from my parents computer" are not valid excuses, but "I have three weeks of chemotherapy" is a valid excuse.


  • Quiz/participation points (PHY 231 only) will be given electronically in lecture using clickers to enter answers. The quiz percentage will be calculated relative to 50% of possible quiz points, QUIZ% = 100 * (quiz points)/(0.5 * possible quiz points). The quiz score will be capped at 100%. Absences for in-class quizzes will not be excused as the 50% base allows for more than a reasonable number of absences.
