Welcome.

In North American schools, students, no matter their age, call each other by their first name.

If you are a freshman or sophomore and are making reference to someone who is a junior or senior, you might refer to them as an "upperclassman."

"Do you want to sit in this section of the cafeteria?"
"No, that's where all the upperclassmen sit; I don't think we'd be welcome."
