Course grade computation

Here are the grades for the course, with names removed. You can use the table below to see how your preformance compares with other students. Each group of numbers are the grades for one student.
• The top row tells the homework grades.
• The second row tells the lab grades.
• The third row tells the major grades of the course: homework, Lab, Midterm and Final Exam. To find which numbers are your grades, look at the midterm and final grades reported on this line (The student marked with an arrow got 24 for their midterm and 37 for their final.)
• The fourth line gives these major grades expressed as a percentage.
• 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" I average, 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. This list is in order of the nice rank.
