transfers for fall 2017

I was just admitted as a transfer for fall 2017, and will be entering as a junior. I am wondering how easy it is to become integrated into the campus and make new friends. Are social cliques formed freshman year, or are people more inclusive and open to new friendships? Is the social scene more group oriented or do people tend to have friends in different places?
Additionally, is greek life exclusive and would it be difficult to get a bid as a junior?

There is virtually no Greek culture at CC. There are a few organizations, and even a few houses, but Greek life at CC is nothing like a typical university.
