Chicago is among the most generous, but many other schools also have very generous need-based aid, and/or also academic scholarships. I found a list here: https://studentloanhero.com/fe...ancial-aid-packages/. There are other lists/calculators out there.
Don't narrow yourself too early; if you need to stay in Illinois, look up all the schools around you to see what they say about financial aid. Keep your grades up and you will have many options.
