I also got my letter today. No, not everyone was placed on the alternate list. I know because I was denied admissions to the program at UCSD. They said it was because I will not be earning a BS degree this spring, so compared to the other applicants, I am still early in my academic career. Surprisingly, I am actually content with this. 🙂 It was a great experience to go through the applications process-- the paper work, the interview, the stressful waiting. 🙂 Good practice for next year. Congrats to all those who got accepted, and also to those who are on the alternate list. It was a great experience this admissions cycle. Best wishes to all in your career development. 🙂
