<p>The main reason the acceptance rate is so high is because there are minimum requirements to even be considered as a UC applicant - what they call “UC eligibility rules.” At other schools, you’ll have a lot of people applying who have no shot of getting in, which brings the acceptance rate down. UC Riverside accepted all UC eligible applicants in 2004, so imagine how many people applied who were not even eligible. Theoretically their “admission rate” should be close to 100%.</p>
