I would keep track of all your financial records and hold onto them until you get into the school of your choice. I would file for extension on your taxes for more time. Once you get into that school they will most likely offer a seminar on taxes and school or they will have free help on campus. Sit in on that seminar and take advantage of the free advice.
Or you could consult a tax professional in your area. Most important advice, keep good records. Recently had a buddy get audited for too many deductions relating school expenses (not sure what), but he said that having his records allowed for an easy audit resulting in just $800 owed. I think it had something to do with interest on his school loans. Good luck
If there are any tax professionals around, I'm sure a lot of people would love to know more about the tax implications of school and how much can actually be deducted. From what I've heard, the tax advantages aren't as good as one may hope.
