Can't Find Classroom

<-NARRATOR:-> Now listen to a conversation between two students on campus.
<-MALE STUDENT:-> Hi, good morning!
Could you help me with something?
<-FEMALE STUDENT:-> Uh...maybe.
What's up?
<-MALE STUDENT:-> Well, I'm a first year student.
<-FEMALE STUDENT:-> Everything going okay?
<-MALE STUDENT:-> Actually no...um.... this is a little embarrassing—
I think I left my class schedule back in my dorm.
<-FEMALE STUDENT:-> Hm.... not a good thing to do on the first day of classes.
<-MALE STUDENT:-> Yeah...so I'm not sure where my class is.
I think I remember it was supposed to be here in Smith Hall.
<-FEMALE STUDENT:-> There is a computer for student use in the student center.
You can go over there, look it up and check the room number.
But...you'd have to hurry.
<-MALE STUDENT:-> Hm ... that's not a bad idea.
I could check my schedule for the whole rest of the day at the same time.
I don't know where any of my other classes are either, but I don't wanna be late, make a bad impression with the professor on the first day.
It's actually my very first class - Introduction to Psychology.
<-FEMALE STUDENT:-> Psychology? Oh! Okay, you're definitely in the right building.
And if it's introduction to Psychology, it's gonna be a big class, in which case it probably meets in a big lecture hall.
There're only three lecture halls in the building, one on every floor.
Just check each floor till you find yours.
There is an elevator, so you should be able to move fast.
<-MALE STUDENT:-> Yeah, but I don't know what the professor looks like or anything.
How will I know whether it's my class or not?
It'd be sort of embarrassing, sticking my head into each lecture hall, asking if I was in the right place.
<-FEMALE STUDENT:-> Well... you might luck out and find it the first time.
