I suggest you read Homeschoolers' College Admissions Handbook by Cafi Cohen. You'll find an entire chapter devoted to finding money for college. Cohen discusses how colleges award scholarships based on academic, athletic, or artistic merit. In some cases, financial need enters in the scholarship qualifications. You can also apply for a loan or student employment.
When you request application forms from colleges, Cohen advises students to ask for scholarship and other financial aid forms at the same time. About 95 percent of student aid is granted by the federal government, state government, and colleges and universities themselves.
