I have listed some CSU admit data and admitted CSU/SLO GPA ranges/averages.
Cal Poly SLO has a projected admit rate for Public Health at 12% and the College of Science and Mathematics SLO GPA admit range (25=75th percentile) is 4.11-4.25.
San Diego State’s Health Communication major had a 73% admit rate and the campus average admitted CSU GPA of 4.06.
CSU Fullerton’s College of Health and Human Development where the Public Health resides had a 85% admit rate with a campus average CSU of 3.68.
San Francisco State is a non-impacted CSU campus so a CA resident with a 2.5 CSU GPA should gain admission.
Good luck and if you calculate out your 3 UC GPA’s and list your applied major, I can post some admit rate and GPA data also.
