Hey sweetchicky,
I don't know exactly how it all works at the school you are transferring to but first off let me tell you that going through rush to meet people is a really good idea. Thats what I did. But basically at UCF its kind of a mutual decision. Each day you attend a certain amount of parties and at the end of the day you rank them on if you would like to go back to that house. At the same time the houses are ranking girls too. The next day you see who you got invites back from. You may not be going to a house that you really liked and you may be going that you ranked lower. Anyways the last day before bid day is preffs. That is the top few houses that you would like to join. And from those few you make your final decision. Preffs is also a formal event. The next day is bid day and you get to see who offered you a bid to join. Well I hope that helps and Good luck.
