Does your father received disability pay in addition to the $33,000, or is the $33,000 the total of all income (taxed and untaxed) that your family receives? Your EFC seems too high. Please post (or PM me, if you prefer):
Parent income from work; student income from work
Parent taxes paid; student taxes paid
Parent untaxed income; student untaxed income
Parent assets; student assets (just what was reported on the FAFSA)
