How many courses did the woman take last semester? Who is the man in this conversation?

W: Dr. Steven, I am thinking about changing my major before the end of the freshman year.
M: What are you studying now?
W: I am taking three general courses and American history and American literature this semester. Last semester I took four requirements and freshman French.
M: I believe it’s not too late to change your major because you’ve mainly taken general requirements which all freshmen have to take. Also we have twelve electives so the two literature courses will be included in them, so you can change your major without losing any credit hours.
W: I am very happy to know I am still able to change my major. I am interested in writing newspaper articles, and after finishing my degree I would like to work for some newspaper firms.
M: Oh, I think you will be a good writer.
W: Dr. Steven, when do students start practical training?
M: They don’t begin practical training in reporting until the sophomore year. Journalism normally is taken in the freshman year as a general background course.
W: I see. I will take the course next semester. Thank you very much for your help.
M: You’re welcome. I look forward to seeing you in my department.
