Why does the woman take Theoretical Dynamics again?

W:Excuse me, Professor Taylor.
M:Yes, Jerry. How can I help you?
W:I need to get your signature on my schedule card here, on the line above advisor’s approval.
M:Sure, but let’s look at it over together first. How many courses do you have here?
W:Six.
M:That’s quite a heavy load. Any particular reason?
W: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. The Introductory Economics is fairly easy and so is the course of Mechanical Drawing.
M:Well, I’ll be happy to sign the card. 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.
