there are no preference lists. everything happens second year. for application sites, the open applications / announce sites around october-ish and selections are annouced beginning of february. shortly after, the lottery happens for everyone that didn't apply or was not accepted to an application site (usually 70%ish of the class). there are not preferences in the lottery. you are randomly assigned a number the day before, and they simply go in numerical order on lottery day and you pick where you want to go from what is left. if you are say #5 you're gonna get your choice, but if you are #120, you are gonna have slim pickings as they say. hahaha after that is the appeals process etc if you have an extreme extenuating circumstance.
that said, i would NOT solely choose to come to WCUCOM based on the fact they have a hubsite in a location you desire. of course take it into consideration, but NO hubsite slot is guaranteed until either your application is accepted or you pick your spot during the lottery!
