Since most of the students are continuing from the previous semester, they have already settled into a routine, made friends, etc. That does not mean you can’t come in and be welcomed and accepted. But it does mean you may have to be more outgoing and assertive about making these things happen for yourself.

I’d suggest researching a couple groups/activities or intermural sports, etc. that you would enjoy and join right away. If you sing or play an instrument, you might join a university band or chorus as a way to meet people with some similar interest. Many schools have ensembles that anyone can join — you don’t have to be a music major.

Good luck!
