IU fraternities and Business School

<p>I am currently considering transferring to IU for the spring of 2013. I am very interested in joining a fraternity,but am not sure if there is a rush period in January. I know a couple of freshman who rushed at the beginning of the school year, but am not positive if there is a rush week at the beginning of the 2nd semester.
May someone please explain to me if there is a rush week after winter break? If not, would incoming sophomores be allowed to rush beginning in the fall of 2013? Additionally, how difficult is it to get a bid? I would like to have a good balance of studying and partying. Is Sigep a good fraternity?</p>

<p>I'm also trying to get into the Kelley School of Business as I am not a direct admit. It is to my understanding that you need to get a "B" or above to be accepted into Kelley. Are the "weed out classes"(M118,M119,Bus K201) that difficult?
Thanks for your help!</p>
