My son is a current CS major at SDSU and will easily graduate in 4 years. He came in with a good amount of AP credit, so he was able to take a slightly reduced course load since CS is very project heavy in the upper division courses. I agree with @NCalRent, that any student can graduate in 4 years if they stay on track with the courses. Some do end up taking a class or two during summer session to make the 4 year graduation target.
SDSU does offer a 4 year plan for each major which you can look up here. Just select year and major: https://sunspot.sdsu.edu/pubred/!mymap.disp
She will also be given a personalized package in Orientation where it lists any AP/IB or DE credit given.
