Joining a German Course

Customer: Hi, I want to join a German course. Can you help me?
Staff: Of course. Please sit down. What is your level of German?
Customer: I think my German is not very good. I know some words and simple sentences.
Staff: Okay, so you are a beginner or elementary level. Do you want to study in a group or alone with a teacher?
Customer: What is the difference?
Staff: In a group, you study with five or six other students. It is cheaper and you can practice with other people. With a private teacher, you study alone. It is more expensive but faster.
Customer: I think a group is good for me. How many times a week are the classes?
Staff: We have classes two times a week or three times a week. What is better for you?
Customer: Three times a week is good. I want to learn fast.
Staff: Great. The classes are on Monday, Wednesday, and Friday. They start at 6.30 p.m. and finish at 8 p.m.
Customer: That's perfect for me. How much does it cost?
Staff: It is 80 euros a month for three classes a week.
Customer: Okay, that's fine. How many students are in the group?
Staff: Maximum six students. Now we have four students in the beginner group.
Customer: Good. When can I start?
Staff: You can start this Monday. Come at 6.15 p.m. to fill in a form.
Customer: Perfect. Do I need to buy any books?
Staff: Yes, you need one book. It costs 15 euros. You can buy it here on your first day.
Customer: Great. My name is Anna Brown. Can you write it down?
Staff: Of course, Anna. We will see you this Monday at 6.15 p.m.
Customer: Thank you very much. Goodbye.
Staff: Goodbye. See you Monday.
