^^ I am curious too, unless they counted all the extra costs associated with transportation/visits if the school is far away?
I pay sticker price (OOS) for my freshman. But with all the visits, moving in-out, it would probably be another 10K (Just the parent weekend alone, cost us $2000 for air tickets and hotel room (still ended up not be able to go :-(. Thanksgiving ticket for her to be home is $1000 round trip). I still hope to keep it all under 75K. Thank goodness for 529 account and the decision we made when she was born 18 years ago to save for college, even when we were making no where near 100K combined income.
