I think the chart you are looking at for computer science is a profile for holistic review students. Everyone who gets a 3.5 GPA and above is automatically admitted. Kids who have a GPA below 3.5 go into holistic review. The holistic review students admitted to CS in spring 2017 had cumulative GPAs ranging from 2.59 - 3.48. The kids who had GPAs of 3.5 to 4.0 are not included in that profile.
