Why does the woman take Theoretical Dynamics again? [originaltext]W: Excuse me,

W: Excuse me, Professor Taylor.
M: Yes, Jerry. How can I help you?
W: (10)I need to get your signature on my schedule card here, on the line above advisor’s approval.
M: Sure, but let’s look it over together first. How many courses do you have here?
W: Six.
M: (9)That’s quite a heavy load. Any particular reason?
W: (7)I had to drop my Theoretical Dynamics last semester when I went into the hospital, so I need to take it again.
M: So you’ve already learnt a lot of the material.
W: Right. And a Methods of Mathematical Physics is a part of the third year requirement.
M: Let’s see, Physics, Methods of Mathematical Physics. Oh, I see you’ll be in my seminar of computer science.
W: I’m looking forward to it and the fascinating seminar of optical computer, too.
M: Two seminars? Can you handle the work?
W: I think so. (8)The Introductory Economics is fairly easy and so is the course of Mechanical Drawing.
M: Well, I’ll be happy to sign the card. (9/10)However, I insist that you come to see me after the first week of classes so we can make sure this isn’t too much for you.
