  • Homework assignments: 15%
  • Paper presentation: 10%
  • Reading summaries: 10%
  • Midterm Exam: 20%
  • Projects: 40%
  • Class participation 5%

  • Assignments are due before class on the posted dated. Reading summaries are due at 11:59pm Monday (i.e. the night before class). There is a 25% penalty for up to 12 hours after the deadline.
