Appeal financial aid a second time?

@Knowsstuff sorry, could you please explain what a “lac” is and what housing credit is? If I go to Penn state I’d be paying roughly $10,000-11000 a year including room and board. As of right now, if I go to Fordham University, is be paying roughly $20,000 a year (w/o housing. I’d be commuting and staying with a relative)
