Abstract

It is not uncommon for students to try, and indeed to succeed, in buying the course texts used. This often makes a great deal of sense. But for this course, you must buy the textbook new . Here's why. The textbook comes with software that you will use to submit all of the course homeworks. The problem is that only one student can register the software , per book — period. So, if you buy the textbook used, not only do you run the risk that the software won't be intact, you will be unable to register the software and, therefore, unable to turn in your homework.
