Exam 1 Results
Exam Given: September 16, 2009 : Scores Posted: September 21, 2009

Check your overall class score. Includes attendence, Exam1, and extra credit points up to the date Exam1 was administered. Below is the distribution of Exam1 scores, from which you can see how you performed relative to the class. The plot is the number of students with a score in a 5 point bin. For example, if you got an 73 on the exam, you are one of the students contributing to the bin 70-74.
Letter grades are not provided on your exam because your letter grade in this class will be determined by the overall distribution of points at the end of the semester. However, you can see where you fall within that distribution at this time. Recall that your lowest midterm exam score of the four will be dropped in the computation of your total points in the class. In my grading system, those students just above the class average usually end up with a grade in the low "B" range. For this exam, the average is 64 and the standard deviation (spread in the average) is 14. According to the curve I usually apply, for this exam score distribution, I would roughly give letter grades as 55-69 is a "C", 70-84 is a "B", and 85 and above is an "A", etc. But as I said, those letter grades mean very little at this time. You grade in this course will depend upon the distribution of the total weighted score at the end of the semester.

NOTE ABOUT NOT HAVING TO TAKE THE FINAL EXAM. Four (4) students earned a 90% or above. Congratulations! These four students are now eligible for the opt out of the FINAL EXAM so far.
