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 the following:
Assignments 10-20%
Project 10-20%
Tests 30-50%
A minimum of two tests will be adminstered during the semester.
Final Exam 30-40%
