Any class of 2011 senior who wants to apply for college financial aid should now be completing the FAFSA form, availalbe here. But here's a common mistake you can easily avoid.
"You" and "Your" refers to the student, not the parent, unless the form specifically says otherwise.
The FAFSA is written with the assumption that the student–not the parent–will be the one completing it. But that's often not what happens. Many parents fill out the FAFSA for their kids, which is fine, as financial aid is the one part of the college application process where I think it can be a good thing for parents to jump in and help or just take over completely.
So parents, if you're completing the FAFSA for your student, remember that the form wants your student's information (name, birth date, social security number, etc.) until you get to the section that specifically requests parent information.
