This is something to think about also: when I went to Columbia's open house, they flat out said that even if they love your work, if they don't think they can help you, they aren't going to accept you. Now, that obviously doesn't necessarily mean that you're ready for shows in Chelsea. It just means that these "rejections" have so many different factors built into them, it's not just based on your work. If an institution doesn't think they can offer you anything, even though they might really respond to what you are doing, they won't take you anyway. I've been told over and over again that getting into these programs is like having all these factors align like the stars. Factors which often times have very little to do with your actual work.
