If you’re a CSU student, you can take a single online course through any of the CSU’s 23 campuses concurrently with your home Fall and Spring CSU courses. (If you are interested in taking Summer courses, click here.) A “single online” course is any class that’s offered in a completely online environment, no in person or on campus meetings. Many courses are offered in an asynchronous learning mode, meaning no scheduled meeting or exam times.
