What was your major you applied for and what were your stats? Have you heard back from the admissions office for Fall 2015?
I’m not appealing, but I’m a UCSB student currently and we admitted around 22,000 undergrads for about 5,000 spots. Granted, people love to choose other schools over us, but I’m afraid the numbers seem to be somewhat aganst you 
Good luck, and hopefully someone who appealed gets back to you!
