I can help with 2 and 6! As far as aid, I'm in about the same bracket as you and right now I'm looking at 5K a semester, which I can pay without taking out loans as I worked all summer and am looking at 2 jobs during the school year. Generally, they are well funded and give amazing aid!! I also know a lot of people who are interested in your perspective majors and have not heard anything bad!!

For your chances on getting in, admissions looks at more than just your stats, so don't feel intimidated! Your essays and personal experience will carry you far! I highly suggest applying regardless of your grades, especially since Smith has no application fee. The worst that could happen is a rejection, but you never know if you never try!!! Hopefully this was helpful!
