How good is this? What can it be translated to in money terms?
If your FAFSA EFC is 1535, you would get about $4000 or so in Pell Grant money. That is the only guarantee.
It looks like some of your schools use CSS Profile, so those schools will use those calculations to determine your aid.
And those schools will include the about $4k in Pell grant money into their aid.
If you get into a school that meets full need (which requires high stats), you will get excellent financial aid.
