 Complete Listing of All Scores & Course Grade
 Please note that the Adjusted Course Percent reflects your lowest problem set score dropped. It also reflects your LOWEST Exam 15 score being replaced with the average of that exam score and your two highest exam scores or the average of that lowest exam score and the Final Exam score, whichever was higher. For many of you, this resulted in an upwards adjustment of 14%, based on your own performance in the class.
 I will be oncampus on Wednesday, May 28 from ~11:30am1pm. I have a meeting ending at approximately 11:30, so if I am not back to my office right at that time, I should be soon after. You are welcome to view your final exam at that time, or pick other papers you have not collected. They will also be available for viewing or pickup during the first week of the Fall semester.

Academic Integrity
 Academic integrity is an important issue in all academic settings, and will be taken very seriously by the instructor of this course, and the college generally.
 I recognize that most students conduct themselves with honesty and integrity. I also recognize that the actions of a few dishonest students and the impact of those actions on the academic process necessitate a frank and ongoing discussion of this issue.
 Please review the Student Handbook information on Academic
Integrity.
