II. EXAMS AND QUIZZES
The above values are close approximations, not exact values.
Students are expected to attend all lectures and laboratory sessions. If it is necessary to be absent at any of these sessions the student should make pre-arrangements with the instructor. Particularly if a laboratory session is missed the student must check with the instructor before running any of the laboratory equipment. This is for the student’s personal safety as well as protecting the laboratory equipment from possible damage.
Policies: Students are expected to observe the RICKS COLLEGE Honor Code. This includes: conduct, dress and grooming standards, and observing LDS principles.
Extra credit projects can be arranged if approved by the instructor.
