Course Descriptions

This section includes a brief description of each credit class offered on a regular basis at Green River College. Classes are arranged in alphabetical order according to the college department that offers the class.

Each listing includes a course number (prefix & code/number), course title, number of credits awarded, prerequisite, course outcomes, and academic transfer distributions are also designated where applicable. Common course numbers are identified by an “&” symbol at the end of the department abbreviation.

Course numbers 100-299 are designated for Green River College programs and courses that transfer to senior institutions (transfer is sometimes limited). The 100 series is ordinarily for first-year students and the 200 series for second-year students, but this distinction varies because of differing requirements at other colleges and universities. The 300 and 400 level series are for third- and fourth-year students.

Consult the “Programs of Study ” section of this catalog and your faculty advisor for specific information about each class and about which classes will meet your requirements.
