what is the effect of enrolling in the university on our social life ?

2 answers

What do you mean by "our" social life?

Are you married, with kids?

Are you 19, irresponsible, and prone to act a fool when drinking illegally?

Are you a nun?

So, the term "our" is operative. Look in the mirror at yourself, not at others.
It will also make a difference if you enrolling in a local university or one distant from you home. Would it be state run, private or affiliated with some religious organization?

Would you be pledging a fraternity/sorority? Living in a dorm? Will you join any other campus organizations?

Will your high school friends also be attending that university?

The answers to these questions would effect your social life.
