Yup, do it now. Try to have it done by mid-march. List all the schools you think you have a chance of getting into. I know you can list six schools on the regular form, and then there's a way to add more schools if you need to.
ha. i've been bugging my mom everyday to do her taxes She got so tired of me and finally did it. You actually don't need your 2004 taxes though. You can estimate the numbers on your FAFSA by using the 2003 FAFSA.
