@d33psan Purdue University average financial aid for incoming first year students is $18,891, a significant amount will go to in-state students. Nevertheless, approximately 46% of new students receive some form of financial aid, a large part of which are scholarships and grants. All the scholarship and grant money has been awarded at this time, congratulations based on the numbers you provided you appear to have received OOS merit-based FA. Please confirm.
Your best and really only remaining option is to speak with the Office of Financial Aid regarding a change in circumstances review of need-based FA. While you have to be realistic about receiving additional need-based FA, it certainly is something you might want to do asap, time is unfortunately not working in your favor at this stage of the process. Best of luck and success!
