transferring to university of denver

I am planning on transferring to DU as a sophomore. I am a little worried about adjusting and making friends as a transfer student as opposed to coming as a freshman. How hard would this be? Would i be separated from most sophomores living off campus or in a greek house? How hard is it to rush as a transfer? Are transfer students common?

At DU students are required to live on-campus for their first two years, so there will be plenty of sophomores on campus.
