Being on alternate list is much better than getting rejected for sure. Being "high" on the alternate list is much better than being "low." Most schools who have deposits down for each seat, in other words when they become full. Start making an alternate list, which means that they will rank the other students and put them in order. So you being high on the list means that if enough people fail to register for the 2003 matriculating class then you will be able to take their spot. However, the sad thing is that there is no time frame. It maybe next week, or it maybe the day before school starts.
What I would do it ask the Admission director how many people usually get off the alternate list, and that way you will know. However, you not knowing what number you are will give you a mixed feeling. If you are high that means that you have a good shot.
Cross your fingers.
