I just read an article that I cannot find now that suggests it is wise to ask for more merit aid. I also know personally that my brother has done this for one of his children and she received additional merit aid, but not at Tulane. As DadTwoGirls said, have the reasons that Tulane is a better fit for you ready. There is no harm in calling , I personally would have the parent call as there may be less emotion involved and a basic " we need an additional ----$ or Tulane is not an option. Our child is a great fit for Tulane because…" They certainly won’t rescind your present offer. Go for it! We just returned from Tulane Honors weekend and were very impressed. Good luck!
