The contributions listed do not matter. HDS offers either 100%, 75%, or 50% tuition as need-based financial aid. There's nothing in between. What you get depends on certain income brackets they use. I know HDS does not consider parental income at all, so parental contribution should = 0. However, you should have some student contribution listed if you had income from last year. You can contact the financial aid office and see what they say about this, but they won't offer anything different unless they miscalculated something.
