Exam 2, family emergency

Yesterday there was a family emergency in my family that prevented me from activating the proper exam 2 for you all yesterday at lunch time.

So the exam 2 that everyone took yesterday was the wrong test. Webcourses copied it over automatically from Summer semester when it created our Fall semester Webcourses area. The test everyone took yesterday was a leftover test from Summer!

Many of you have commented on the inclusion of chapter 8 questions and so forth. Now you know why. I usually take these auto-copied exams and revise them with new questions, renumber the questions, take out old questions, make new diagrams, and so on, all oriented to what we do each semester. So what you all had yesterday was fresh for the summer class, but not in synch with this semester's class. It grieves me to read your comments of dismay, and I apologize for initiating this confusion.

So by way of making it up to everybody for the fiasco yesterday, we will have a Chapter 5, 6, 7 do-over exam, Exam 2A, next Thursday, 12:05 PM - 11:59 PM, and we will get our brains re-organized for it. Yesterday's exam 2 score will be erased. Exam 2A will have the usual range of questions, from basic questions all the way up to one or two brain burners; I will append a few bonus questions, too.

I apologize again for the fiasco! But we shall prevail!
