You will be eligible for about $3000 in Pell Grant money and a $5500 Direct Loan. Those are the only guarantees.
Is this a “good” FAFSA EFC? It depends on the costs to attend the colleges to which you are applying, and their policies on awarding need based aid.
$8500 certainly would likely cover all the costs for a year at your instate community colleges. But it won’t cover the cost of attending an OOS public or a $70,000 private university. You would need institutional need based aid to attend those. And that is up to the colleges.
