  • Clicker Questions in class: 5%
  • WeBWorK Assignments: 5%
  • Labs (online and written quizzes): 15%
  • Midterm Tests (20% of the higher mark + 10% of the lower): 30%
  • Test 1 - Saturday, Oct. 20, 2018, 9:30 a.m. - 10:50 a.m. (Lazaridis Hall)
  • Test 2 - Saturday, Nov. 17, 2018, 9:30 a.m. - 10:50 a.m. (Bricker Academic Building)
