I also applied to CU and have not heard anything. I believe last year they sent out a handful of acceptances to their top choices and invited them to a visit. After the visit they go back and fill in the spots of people who decide to go elsewhere and any other spots they may have. Not sure if that is how they are doing it this year but I think that is what they did based on what I have read on previous posts.
Also, if anyone gets any info on Vandy please share.
