Are your parents helping you pay for college? If yes, what is the total your family can pay per year of college?
Agree with the above that UIUC is a reach for CS, probably a high reach. The CS admit rate this year was 4%. Often the CS acceptance rate is lower than a school’s overall acceptance rate (for the schools that admit by major).
There are many public schools on your list, and they tend to not offer much financial aid for OOS students. Run each school’s net price calculator to get your estimated cost of attendance. Don’t apply to any schools that look to be unaffordable.
