FAFSA is an application (Free Application for Federal Student Aid) that you fill out to give information to the colleges and to the government.
If the information on your FAFSA application indicates that you are eligible for federal help, then you might get a little funding from the government. https://fafsa.ed.gov
Based on the information you and your parents provide annually on the FAFSA, the colleges make up a financial aid package of loans, grants or scholarships, if your college has that money.
FAFSA is not a scholarship. It’s an application.
