(c) All grants shall be applicable only to tuition and necessary fee costs for 2 semesters or 3 quarters in an academic year. Requests for summer term assistance must be made separately and shall be considered on an individual basis according to Commission policy. The institution shall determine the grant amount for each full-time and part-time student, which shall be the smallest of the following amounts: (1) $2,000 for 2 semesters or 3 quarters of full-time undergraduate enrollment or $1,000 for 2 semesters or 3 quarters of part-time undergraduate enrollment, or such lesser amount as the institution finds to be available; or(2) the amount that equals the tuition and other necessary fees for 2 semesters or 3 quarters required generally by the institution of all full-time undergraduate students, or in the case of part-time students an amount of tuition and fees for 2 semesters or 3 quarters that does not exceed one-half the amount of tuition and necessary fees generally charged to full-time undergraduate students by the institution; or(3) such amount as the institution finds to be appropriate in view of the applicant's financial resources. "Tuition and other necessary fees" as used in this Section includes the customary charge for instruction and use of facilities in general, and the additional fixed fees charged for specified purposes, which are required generally of nongrant recipients for each academic period for which the grant applicant actually enrolls, but does not include fees payable only once or breakage fees and other contingent deposits that are refundable in whole or in part. The Commission may prescribe, by rule not inconsistent with this Section, detailed provisions concerning the computation of tuition and other necessary fees.
