Fill out a FAFSA (Free Application for Federal Student Aid) application. Federal officials who review the FAFSA will determine your EFC.
Add the amount of federal aid you're eligible to receive to your state and private aid awards.
Subtract this value from your total college expenses, including room and board, tuition, supplies and books. The remaining amount is the portion of EFC you must pay.
Withdraw money from your 529 account to cover remaining schooling costs. The 529 rules allow you to use a 529 account to pay for tuition, fees, books, supplies (such as art supplies) and equipment (such as a microscope), if you're enrolled in a course where they're required. If your school mandates Internet use, you can also use 529 funds to buy a computer and pay for Internet access.
