It's not too late to file for the fafsa, but you should do it NOW, the sooner the better, and you can list up to 6 schools, list all that you have applied to, or the ones you're most interested if more than 6. Plus, once you get admitted that'll be once less thing you have to worry about when getting ready to go. If you are absolutely sure you want to go to school this fall and not wait, I would advise to visit, if anything it shows how serious and interested about their school. Good luck!
