Modes of instruction
  • Class Materials (Slide pdf) will be uploaded in Teams and course webpage at least one day before the class.
  • Students are strongly encouraged to go through the slides once before the class.
  • Continuous evaluation (Surprise Tests) will be carried out in several classes, based on the previously covered materials - so you should always be well prepared.

Grading:
  • Assignments (15 points) - 6 assignments. Average of all assignments will be considered. Assignments are meant for learning and preparation for exams. Students may discuss homework problems among themselves but each student must do his or her own work. Cheating or violating academic integrity (see below) will result in failing in the course. Turning in identical homework sets counts as cheating.
  • Surprise Test (15 points) - A total of 8-10 in-class surprise tests (each 3 points) will be conducted and the best 5 will be considered.
  • Midterm exam. (20 points) - 2 midterm exams will be conducted and average of the two will be taken. Missed exams earn 0 points. No make-up exams.
  • Final exam. (30 points)
  • Project (20 points) - Quality of work (5 points), Quantity of work (5 points), Report (5 points), Presentation (5 points).
