“No budget but hoping to receive aid”
What does this mean? Have you used the NPCs to see if you would possibly qualify for FA? Are your parents willing/able to spend $70,000+ per year?
Did you explain to your mom that you don’t want to apply ED to Vandy?
Take a look at Barnard. You can also take classes at Columbia and the social lives are very intertwined.
Some other schools to look at are Northeastern, BU, Georgetown, the U of Rochester (not sure about the major), GW, and possibly some of the LACs (not sure if they are too small for you…Barnard is different due to its location and relationship with Columbia).
Your ED philosophy is really not the best. You need to do the research and find a school that is a fit for you. Why is Dartmouth your “dream school?”
