looking at ur predents page, u have great stats, I'd say you definately will get more interviews and most likely many acceptances when that Dec 1st day comes.
However, theres always that "you never know" scenerio, so if I were you, I would just keep that interview in the case where things don't go your way. I know several of my friends with similar stats as yours not getting in last year which was really weird.
In terms of the pre-reqs, dont' let that deter you from going to the interview. There were several people that took classes in the summer to fullfill them, or they even took a really easy online class, or at a community college. Once ur in, its really easy to just finish them.
