Financial aid refers to funds which are used to assist students to cover college fees such as tuition, books and housing. It may be on the part of the government, colleges, or voluntary organizations. Probably, grants (free money), scholarships (merit or need), loans (pay back later), and work-study (part-time campus jobs) are some of the types.
In order to apply, the majority of students complete the FAFSA (Free Application for Federal Student Aid) on-line. After receiving it, you will know what type of assistance you can get.
