Yes. If your family is middle or working class (65k/y or under) you’d get a full ride, need based scholarship.
Then each income bracket is asked to contribute an increasing percentage of their income+savings+ assets.
However if your family makes 250-300k but they dont want to pay for college, you have 6 years during which either you get a merit scholarship at colleges that offer those or cannot attend college at all.
Each student must run the NPC to see whether Duke orbother colleges are within budget.
