Preparing for college is stressful enough, but figuring out how to pay for it is even harder. Plus, from the first FAFSA through graduation, you're sure to be bombarded with financial aid acronyms and buzzwords. Here are some key terms you'll need to know.

AGI: Adjusted Gross Income. Most financial aid forms require parents or students to state their taxable AGI based on income minus maximum allowable adjustments.

Alternative Loans: These private student loans from banks or other lending institutions are not federally supported or guaranteed. Students must be enrolled to apply for these loans.

Capitalized Interest: Unpaid interest that is added to the original amount of a loan. Capitalized interest increases the size of a loan, because the borrower is paying interest on their interest.

COA: Cost of Attendance. This is the total cost of attending a college or university, including tuition, room and board, books, lab fees, transportation and basic living expenses.

CSS Profile: The College Scholarship Service Profile is a financial aid form that many colleges and universities use to determine how much non-federal financial aid a student may be eligible for.

Community College: Sometimes called junior college or two-year college. Students can take classes, and then transfer to a four-year school, or they can earn certificates, diplomas or associate's degrees.

Credit Hour: Credit hours are units of value given to classes. Some classes may be worth two or three credits, while others are worth four credits. Credits vary by class and by school. Many schools base tuition costs on the number of credit hours taken. Some charge a specific dollar amount per credit hour.

Deferment: A deferment is an approved postponement in repaying a student loan. For example, students may seek a deferment on undergraduate loan payments while in graduate school.

Department of Education: This government agency administers several federal student financial aid programs.

Direct Loan : The U.S. Department of Education's loan program.

EFC: Expected Family Contribution. This is the number that's used to determine your eligibility for federal student financial aid. This number results from the financial information you provide in your FAFSA, the application for federal student aid. Your EFC is reported to you on your Student Aid Report (SAR).

FAA: Financial Aid Administrator. An FAA is a college or university employee involved in the administration of financial aid. Also known as financial aid advisors, officers or counselors.

FAFSA: Free Application for Federal Student Aid. Filling out a FAFSA form is the first step in the financial aid process. To be eligible to receive federal financial aid, a student must complete a FAFSA.

Federal School Code (also, Title IV Institution Code): Each college, campus or program has a six-character institution code. You must include the code related to each of your college applications when filling out a FAFSA. These codes are available by contacting the school or checking an online listing.

FSEOG: Federal Supplemental Educational Opportunity Grant. This federal government program provides need-based grants to low-income college students with the most need, and is administered through the school's financial aid office. Not all schools participate.

NSLDS: National Student Loan Data System. This U.S. Department of Education database allows students to access their Title IV student loan and grant information.

Pell Grant: Federal Pell Grants are a federal program that provides need-based educational grants for low-income students. Because they are grants, they do not have to be repaid.
