You can submit your FAFSA right now and add your top 10 (i think) schools to the FAFSA. I recommend you do it ASAP since some schools do offer grants and those are first come first served
also if you interviewed at UCSF, they should of told you that they recommend you do all the FAFSA and supplemental financial aid stuff as soon as possible if you want to see your complete financial aid in december should you be accepted
