This coming Sunday, there will be free help to students around the country in filling out the federal student aid forms (FAFSA). College Goal Sunday will be observed this year on February 8th at locations all around the country. Find the place closest to you and contact them about getting assistance on the 8th.
Even if you can't get there Sunday, the College Goal page is a great source of information. For instance, did you know that you can apply for FAFSA even if your parents are undocumented? Or the newest online practice sheet? The blog page is a cornucopia of goodies for families and students.
And while you're at it, check out this listing of state student financial aid. Many states have financial aid unique to their students.
