Replying to Difference between Community College and a University

I'm currently a freshman at a Community College and its really not that difficult. Just a lot of homework. The only reason why i went to Community College rather than a university is because my generals would be cheaper to get done their.

Now my question is how much different is Community College compared to a university? Like difficulty, atmosphere, and types of people. I'll probably be transferring to a university in about a semester or two and i kind of just wanted to prepare myself if it is quite a different change.
