Pretty much all the pure merit base scholarships at UIC come from Honors College. There are some scholarships which are associated with a degree/specific academic college and they come via the college. To be competitive for Honors College, you will need an ACT score of 28 and be in the top 15% of your class. Some of the scholarships do require that you are an Illinois resident. You will need to fill out FAFSA to be eligible for all potential scholarships and grants.
UIC, like most public schools, don’t offer many scholarships.
