What is the most FAFSA applicants have qualified for?

I'm not sure exactly what you're asking, but when you fill out a FAFSA, you are given an EFC (expected familial contribution) that is based on the information you provide. The FAFSA itself is not a grant/loaning body..but a metric by which to assess what federal/state grants you qualify for, and for your university to determine your "need" (this is a highly contested value, and varies school by school). My EFC is 0 (and my university has a large endowment) so I have received a full ride. Hope this helped!
