You will not know if you qualify for a Pell Grant to accept unless you apply. No matter what your income may be, just about all colleges and universities require you to apply if you want any type of aid, to include scholarships. The deadline for early decision is generally around March 1 each year. Once yor form is completed, it will be sent to each school listed. You can list up to 10. Each school, if applicable, will offer you different amounts. Some may need additional forms. If you do not receive what you think you should get, there are forms to fill out for explanations.
Moving forward, if you do not qualify for a pell grant, a federal loan will be offered as well as a possible work-study. You will receive an email to the email given whether you accept or decline what is being offered...your choice. Make sure, if additional information is needed, you have everything handy. Funds run out quickly, pending the school, and it is best to get everything turned in as early and accurately as possible.
Honestly, as expensive as schools are, a pell grant will not cover your total costs. There are school grants and scholarships I encourage you to apply for.
These are two websites for grants and scholarships and you can filter for the school. Whatever you do, try to leer away from loans. These you have to pay back. Hope this information helps
