Attendance is a course requirement. The final grade may be UN if more than 30% of classes are missed or if less than 70% of items for evaluation are undertaken.
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 criteria:
1.Tests: 0-60%
2.Mid-term: 20-30%
3.Class participation: 0-5%
4.Attendance: 0-5%
5.Final examination: 20-30%
Students are required to supply a three-ring binder, paper, pen, pencil and a scientific calculator with direct algebraic logic (D.A.L. or S.-V.P.A.M.).
A textbook, such as Intermediate Algebra by Marvin L. Bittinger, will be available on loan from the library to students. A course pack may be required and purchased from bookstore.
