I am not clear about your financial status. What is your EFC for all of these schools? Have you run NPC for these colleges? From what you have written here, it seems you are only able to afford about a third of the annual cost but that you are not likely to qualify for enough aid. Is this the case? Do you need merit aid in order to attend?
Yes, a lot of those schools meet full demonstrated need, but it would be very helpful to know if you will qualify for FA. Please clarify. Because it seems to me that you need a HUGE merit award somewhere. There are no merit awards at Amherst, Columbia, Wesleyan or Yale.
If you will qualify for need based aid, your list is ok, though merit scholarships at GWU are hard to get.
I suggest adding Kenyon to your list. They have a few very good merit awards for top students. I also suggest Bates, if you qualify for need based aid. They have an enthusiastic ballroom dance group.
There are a lot of other schools we can recommend, but we do need more info about your financials.
