If a resident of Illinois qualifies for admission to a public community college under Section 3-17 but does not qualify for financial support under Section 6-1.5 or 6-2, that person may be enrolled in the college upon payment of the difference between the per capita cost as defined in Section 6-2 less any payments toward noncapital expenditures received from State and federal sources for the previous year except grants through the State Board as authorized in Section 2-16 or 2-16.02, as the case may be, converted to a semester hour base, and the combined rate of State grants other than equalization grants for the current year as authorized in Section 2-16.02, notwithstanding tuition limits of Section 6-4. Subject to Section 3-17, a public community college may accept out-of-state students upon payment of the per capita cost as defined in Section 6-2. Notwithstanding the provisions of this Section, the out-of-district or out-of-state tuition, whichever is applicable, may be waived for a student who is employed for at least 35 hours per week by an entity located in the district or is enrolled in a course that is being provided under terms of a contract for services between the employing entity and the college.
