Quiz and Exam Scores

The University of Iowa has a privacy policy on distributing student grades and scores. In the past, we have posted grades by using the last few digits of the student ID number, thinking this assured privacy. Unfortunately, there is reason to suspect that student ID numbers are not as carefully guarded as they should be. Therefore, all scores in this course are listed by pin number which is a personal identification number issued by the course professor. To obtain your pin number, please see the professor during office hours or after class.


Final Grades based on the totals below, separated into undergraduate and graduate tables.

Below are the total score calculations, separated by undergraduate and graduate students into two tables.


   NB.  Project counts 50%, Quiz counts 20%, Exam counts 30%
   ToGr =.        (PrTo * 500 % hisco PrTo)
   ToGr =. ToGr + (QTo * 200 % hisco QTo)
   ToGr =. ToGr + (ExTo * 300 % hisco ExTo)
   NB.  Make table of Quiz, Exam, Project, and weighted Totals 
   Gr =. 22 1 $ (0 { |: PrGr)
   Gr =. Gr ,. QTo ,. ExTo ,. PrTo ,. ToGr 

Here are the undergraduate score results.

Below are the quiz scores. In the listing of scores, two scores are not in the range 0-10. The score _1 indicates the student did not take the quiz, but was absent for a good reason (a legitimate excuse), so the score will eventually become the average of other quiz results by that student. The score _5 indicates that no quiz was received for the student, either because of absence, or perhaps because the quiz was given earlier in the hour than when the student arrived.
