My younger son just got admitted to RU Engineering as well as a PSU and Pitt. Now he is waiting to hear back from the privates(MIT, JHU, Upenn, BU and Tufts).
While RU is first choice for him against PSU and Pitt, if he gets into Upenn, MIT or BU its going to be tough to convince him to pick RU. Even if he has to pay the diff in cost, he feels like for what he wants to do, the opportunity advantage provided by those schools outweighs the cost. Of course the fact his older sister also went to RU probably has some impact as well....
