April!? Poet, you need to get the FASA in pronto, it's not an endless flow of money in Washington (depite popular opinion). It's pretty much first come first serve. Your still okay right now, but I wouldn't wait any longer then late March. I called them so this info is straight from the horses mouth.
First of all, if your looking for financial aid (free money you don't pay back) or loans (money you do pay back with interest) you have to fill out the FASA application for every school. You can start sending it out as of around Jan 1st 2000. I sent mine out about 2 weeks ago, because I wanted to wait till I had my taxes done. If you complete your taxes first, it makes filling out the FASA app a little easier. Once you send it in, the gov processess your app for about 1 month. They then send a print out to the schools you select on the FASA app, informing them of all the wonderful money that awaits you including aid and loans, grants. The school's financial aid dept then compiles the info and proceeds to send you a packet telling you which aid, grants, loans, scholarships etc.. you are elegible for. You then select what monies you would like to recieve and reply back to the school.
I hope this helps. As I always say, when in doubt contact the ones who know best. There's a toll free number for help. I didn't have to wait on the line too! long.
