I have a whole backstory for this but here’s the basic question: On Common App, I clicked “No” for if I was applying for need-based financial aid, but I actually do need to apply for financial aid - can I still send FAFSA and CSS Profile to these schools and still get financial aid?
Yes, but you also need to contact the admission(s) office and let them know.
Contact admissions at all of your schools and ask that this be changed to YES.
