According to UIUC’s net price calculator at https://secure.osfa.illinois.edu/NPC/NPC.asp , an Illinois resident dependent student majoring in computer science or mechanical engineering with a FAFSA EFC = $0 will see a net price of $15,197. For a history or math major, the net price shown is $13,045 (i.e. looks like different prices for different divisions based on major). That is still probably more than the student can come up with from federal direct loans and work earnings.
