In general, both sections did pretty well on this exam. The mean was significantly higher than on the first two exams (on the order of 75% (26.5 pts) -- this is great because when I teach upper division courses, the means are typically around 60%!). So, good job! Please read the information below regarding your score on the test (you should refer to the posted scores in McCarty for your scores on Exams 1 and 2). Also read the blurb on the distribution that is posted.
SCORES:
I've posted your scores from Exam 3. As you will note, there are a number of problems with the attached data. It is YOUR responsibility to check the accuracy of these scores and see me (Dr. Osenberg) IMMEDIATELY if there is a problem.
Pay particular attention to the following problems:
1) Missing test scores. If one of your scores is not posted, and you took the exam, you should be very concerned.
2) Missing or incorrect SSN. If the SSN is incorrect, please let Dr. Osenberg know ASAP.
3) Missing exam codes. (Ann and Dr. Osenberg have taken care of these errors. For Exam 4, be sure to pencil in your exam code.)
4) You can check your exam and keep your copy of the test by seeing Ann or Dr. Osenberg during their office hours. If you are in Period 5, please first see Ann to go over your exam or discuss the above problems. If you are in Period 3, please see Dr. Osenberg.
6) ALL PROBLEMS MUST BE RESOLVED BY APRIL 11th. So please check out your scores and test at your earliest convenience. Dr. Osenberg will have additional office hours from ~8-11 on Friday, April 4th (in addition to his regular times on Wednesdays) to help you meet this deadline.
DISTRIBUTION OF TOTAL SCORES:
1) I've posted the distribution of total scores (the sum of the first three exams). However, please note that due to the problems with scores and the incomplete records that we have, I decided it was most useful to use only the scores that were "complete": i.e., where I had a test score for all three exams. If a student did not have a score for any one of the exams, I did not use their total to construct the distribution (I'm hoping that most of these problems will be resolved, and if I had included them, it would have given an erroneous picture of the lower part of the curve).
2) Please use this curve to help you judge your performance up to this point. A VERY CRUDE measure of how you are doing can be judged relative to the performance of the top students in the course. For example, the top ten students have a mean score of 97.3 points (out of 105), and 90%, 80%, 70% and 60% of this is ~88, 78, 68, 58. Anyone scoring below a 60 thus far is in real trouble (i.e., certainly on their way to a D if not an E); and anyone scoring in the 60's should also be very concerned (e.g., on their way to a C or D). While it's impossible to know where the final breaks will occur or how you will all do on Exam 4, I hope this gives you a basic guide, especially for those of you who are not doing well and might be thinking about dropping the course. Of course, anyone who hasn't mastered the material should come to Ann's and my office hours (or make an appointment if you have a course during our scheduled times).
3) After Exam 4, Dr. Jones and I will meet to assign grades. Grades will be based on a curve (a separate curve for each section), which will be decided upon after the results from Exam 4 are known (thus, be aware that the guide above is extremely crude and shouldn't not be used to indicate whether you should expect any particular grade).
