Western Michigan University Recruitment?

I'm a junior and was wondering how competitive WMU's greek life is and if there is any way I could get a bid with my class standing? I plan on rushing in the spring since I couldn't this fall because of work. I hear a lot of the sororities do COBs in the spring. Is this true?? Also I'm a junior but I'm in a program that takes longer and I won't graduate next year. I don't know if that helps. Thanks.
