🏛️ Your state's public flagship
Rutgers University-New Brunswick
The in-state tuition gap is the flagship's biggest draw — most in-state families pay far less than the out-of-state sticker. Average net price after aid runs about $24,406/yr. Admission odds depend on your student's GPA and test scores, not which high school they attend.
Source: IPEDS admissions, tuition & enrollment + College Scorecard net price. Flagship = the state's primary public research university.
