This is a letter-graded course. Assessment will be in accordance with the Douglas College Evaluation Policy. The instructor will present a course outline with specific evaluation criteria at the beginning of the semester. In this course, instructors may use a student’s record of attendance and/or level of active participation as part of the student’s graded performance. Evaluation will be based on the following:
| Lab reports and lab quizzes/activities | 25% |
| In-class participation | 0-5% |
| Homework and/or in-class activities | 0-25% |
| Tests (minimum of two) | 20-35% |
| Final exam | 30-40% |
| Total | 100% |
Notes:
A student who misses three or more laboratory experiments will earn a maximum grade of D in the course. If a student arrives late, impaired, unsafely attired or otherwise unprepared, they may be subject to a mark penalty and/or may not be allowed to perform the experiment at the discretion of the instructor. If a student is not permitted to perform the experiment, this absence is considered a missed lab.
A student who achieves less than 50% in either the lecture or lab portion of the course will earn a maximum grade of D in the course.
