All non-loan aid received by the applicant, except a Maryland Community College Promise Scholarship awarded under Education Article, Title 18, Subtitle 36, Annotated Code of Maryland, shall be credited to the applicant’s tuition before the calculation of the grant amount. A grant shall apply toward the student’s tuition in the lesser of: The amount of the student’s unmet tuition; or As applicable, up to one-third of: The in-county tuition charge at a community college; or The resident undergraduate tuition charge at a public senior higher education institution. If a student is not eligible for in-county tuition at a community college but is eligible for in-State tuition at a Maryland public institution of higher education, the award amount calculated under §B of this regulation shall be applied to the recipient’s out-of-county tuition charge. The grant may be used only for tuition and may not be used for fees or other charges or expenses related to attending an institution of higher education.
