Grading:
  • Assignments including recording (10 points) - Average of all assignments will be considered. Assignments will include associated recordings. Cheating or violating academic integrity (see below) will result in failing in the course. Turning in identical homework sets counts as cheating.
  • Midterm exam. (20 points) - 2 midterm exams. Missed exams earn 0 points. No make-up exams. An average of the midterm scores will be considered.
  • Surprise exam. (20 points) - 8 surprise exams. Closed book. 10 minutes per exam. Each surprise exam is worth 4 points. Missed exams earn 0 points. No make-up exams. The total surprise exam score sums your 5 best surprise exam scores (we ignore three worst scores). Class attendance is mandatory. Unexcused absences get an automatic exam score of zero for that session's exam grade.
  • Final exam. (35 points)
  • Project (15 points) - Quality/Quantity of work (5 points), Report (5 points), Presentation (5 points).
