Course grade computation

98 10:15 am)

The top row tells your homework grades.
The second row tells your homework ranks: top score is ranked 1; worst score is rank 19
The third row indicates the worst-ranking homework grade, which was omitted from the averaging.
The fourth row tells the lab grades.
The fifth row tells the major grades of the course: homework, Lab, Midterm and Final Exam.
The sixth line gives these major grades expressed as a percentage (with the worst ranking homework dropped).
The last line tells your class rank for the major grades. The lab rank was artificially set to 1, because the lab grades are clustered close together and the ranking has little meaning.

Off to the right are your worst rank among the preceding 4 numbers, your weighted average course grade, your rank according to this average, a "nice" weighted average, explained below, your rank according to the nice average, and your letter grade.

The major grades were weighted 5, 3, 2, 4 for homework, lab, midterm and final. To determine your "nice" average, I decreased the weight for your worst-ranking component by 2. Thus if your worst ranking component was the midterm, I dropped the midterm grade. If it was the final, I reduced its weight from 4 to 2. The list below is arranged is in order of the nice rank.
