From what I understand from the school's info sessions, you should do the FASFA now and send it to all of the schools that you are applying for. Once you have online form filled out, there's a pulldown menu for adding the schools. I don't think there's a problem with preemptively submitting. Doing so now means not having to do go back to the FASFA again, scramble to do so once you have an invitation from them, or worry about missing a deadline. People please correct me if I'm wrong. Thanks.
