Our EFC with two in college was 120% of what EFC for one in college. The COA was slightly different at each school, and that was reflected in the types of monies that were included in the FA package. We were close to full pay with one in school, but fortunately S1 had merit money to help offset that. With two in school, the merit $$ meant he got less FA than his brother, but was still about the same total cost.
