How do i search for open groups on Facebook?

[BLUE PIXEL]

Most of the groups i have searched on facebook are closed. I want a list of groups that are open only in my search. How do i do that?

You will have to keep searching for that.
Try searching for groups that are made for activities that suit your interest like gaming or some other sport. If you are keen you can start your own group maybe for your class and you can add people.
