REQUIREMENTS: 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 chedk 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.
PREREQUISITES: Concurrent enrollment in ME 131
