Evaluation will be carried out in accordance with Douglas College policy. The instructor will present a written course outline with specific evaluation criteria at the beginning of the semester. Evaluation will be based on some of the following:
Weekly tests | 0-40% |
Mid-term tests | 20-70% |
Assignments | 0-15% |
Attendance | 0-5% |
Class participation | 0-5% |
Tutorials | 0-10% |
Final examination | 30-40% |
