M: The job sounds great, but I’m a little worried about how much time it might take.
W: It’s pretty reasonable. It never took me more than five hours a week to do all the grading and then another thirty to forty minutes to record the grades on the computer.
M: That sounds manageable. I guess you can do the work when it fits into your own schedule, too, can’t you
W: Oh, yah, you can do the grading in your room or in the library. You just need to get each set back for the next class, but that means you always have at least two days and sometimes four.
M: It sounds great.
W: Good luck with your interview.
