What does the woman think of the math teacher?

M: Lucy, you’re back. How was your first day of school?
W: It was great. I had a really good time.
M: What do you think about the teachers?
W: To be honest, I like all of them, except for the math teacher. Though he must be quite young, he seems like an old person. (1) He’s so boring!
M: That’s too bad. How was your English teacher?
W: She was great. (2)In today’s class, she gave us a lecture on how to be a good student. She told us not to cram for exams, and to pay more attention on communicating than memorizing.
M: Were you able to understand everything that she said?
W: Not everything, but nearly. She speaks very clearly and doesn’t use very complex words so that it is easy for us to understand her.
M: She sounds like a good teacher. Do you think you’ll pass her class?
W: Yes...with flying colors!
M: What does that mean?
W: It’s a new phrase that she taught us today. (3) It means that I will not only pass the class, but I will do extremely well!
M: I’m sure you will.
W: I hope so.
M: Did she give you any homework?
W: Not today. She said she wanted us to relax tonight instead of doing homework.
M: No wonder you like the class so much.
