The average GPA of incoming freshmen at UC Riverside (UCR) isn't publicly released as a single, precise number. UCR, like many universities, publishes ranges or percentiles of admitted students' GPAs rather than a straight average. This is partly to avoid the oversimplification of a single number and because the GPA calculation methods vary among high schools.
To find information on the academic profile of admitted students, you should check UCR's official website, specifically looking at admissions statistics or freshman profiles within the admissions section. These often include GPA ranges or percentiles for admitted students.
