At Pasadena City College, college algebra for STEM majors is labeled Math 003. At Cypress College, it’s Math 141 C and at Napa Valley, it’s Math 106. For anyone hoping to enroll in the same course at Oxnard College, look for Math R115. At Cuyamaca College, try Math 175. And at College of the Sequoias, it’s Math 035. On and on across California’s public community colleges, courses that basically cover the same material and are recognized as being interchangeable in fulfilling requirements for majors and transfers are assigned different course numbers. That process confuses community college students trying to transfer to a four-year university, critics say. Students may not know whether they are taking the right courses and may inadvertently repeat some if they take classes at more than one community college, either in person or online.
