Semester units vs. quarter units
ARC, CRC, SCC and FLC are on the semester system, that is, we have a Fall semester which starts in August, a Spring semester, beginning in January, and a summer session starting in May.  Some transfer schools, including all the UC's are on a quarter schedule and have Fall, Winter, Spring and Summer sessions.  The tool below allows you to convert between semester and quarter units. Remember when converting you are not losing or gaining any units, you are simply changing them from one format to another.
