No, but if you are offered and accept admission, you must have completed it by the time you matriculate.
If you have yet to complete or enroll in a course, California Virtual Campus is a great resource that lists online courses offered at colleges and universities in California. You can also look at online courses at Excelsior College, UCB Extension, University of Massachusetts, Portage Learning, and/or University of Phoenix
The course must be completed at an accredited college or University that results in credit on an official college transcript (online courses that earn credit on an accredited college or university transcript meet this requirement). Applicants must provide evidence of completing this requirement for admission by providing the college transcript that displays the statistics course grade and credits earned. Receiving a 5 on an AP Statistics exam also satisfies the requirement.
