W: Hello, Ben. You're getting ready for tomorrow's lessons, aren't you?

M: Yes, but I'm a bit nervous. I have no idea what'll happen in class and how I'll get along with my classmates.

W: I understand how you're feeling. Just take it easy. You'll make a lot of friends very soon.

M: Thank you. I'll try my best to get used to my new school life as soon as possible. By the way, what time does the first class begin?

W: At 8 o'clock. But before that we have 10 minutes to hand in homework and then 20 minutes for morning reading.

M: So we must get to school before 7:30, right?

W: Right.

M: How long does each class last?

W: 45 minutes, I think, with a 10 or 15 minutes' break.
