Results for Exam 3

This webpage will give an overview of how the class performed as a whole on the exam. You can find your individual score posted on Blackboard. When you get the exam back in class, double check that the score on your paper is the same as what is recorded on blackboard. Also, add up your points for the entire exam and double check that I have the right total for your paper. I am very careful totalling and recording scores, but mistakes CAN occur.However, I am a bit concerned that several students have seen a steady decline in their exam scores. Part of this may reflect increasing difficulty of the material. But judging from the results on the exam, it appears that some students who did well at the start of the course were not fully prepared for this exam. I suspect that some students have not been keeping up with homework, and have been coasting for the last few weeks. If you are such a student, and if your exam average has fallen below 80, I strongly urge you to rededicate yourself to doing the assignments. With a poor showing on the final exam you could end up with an unsatisfactory course grade.

**Part I Multiple
Choice**

For example, if you had 5x's, your raw score was 31 and your adjusted score would be (31)(.75) = 23.25. Rounding (up) to the nearest half point gives 23.5. Your paper indicates the number of x’s for each numbered problem, but does not tell you which statements were correct or incorrect. This is intentional: Your Exam Solutions groups will need to discuss the multiple choice items and come to some consensus about which statements are true, and why.

Part II Problem 3

Each part a through f was scored on a scale of 0 to 10. This gives a maximum possible raw score of 60. The raw score was multiplied by 21/60 and then rounded to the nearest half point. For example, a raw score of 52 would produce an adjusted score of 52(21/60) = 18.2, which is 18 to the nearest half point. Adjusted scores ending in .25 or .75 were rounded up to the nearest half point.
