- Category:
flagship_public
- The dramatically lower CS acceptance rate (~7%) vs overall (~42%) is a key characteristic. For the simulation, using the overall rate is appropriate since we model university-level admissions, but the notable field flags this.
- Strong in-state bias (71% of freshmen are Illinois residents)
- Very generous financial aid for low-income students ($3,883 net cost for <$30K)
