Grants are money given to help students based on need and other eligibility factors. Grants do not have to be repaid. The amounts vary from year to year. To be even considered for grants, you have to fill out your FAFSA each year.
Federal Pell Grant
Up to $5,920 for 2017-2018 depending on financial need as determined by the EFC from your FAFSA. To get the full amount, you have to be enrolled full-time, but even eligible part-time students get a partial grant.
Federal Supplemental Education Opportunity Grant (SEOG)
The amount varies based on exceptional need, Pell Grant eligibility, and the amount of money appropriated by Congress for the current budget year.
