HOW GRADES WERE ASSIGNED IN EECS 206:
1. I compute the weighted sum of the exams, labs and homework.
For the relative weightings, see the introductory handout.
• Actual figure is the sum of the following:
• Exam #1 score. Maximum=100; counts 20%
• Exam #2 score. Maximum=100; counts 20%
• Exam #3 score. Maximum=150; counts 30%
• Lab Reports.     Maximum=100; counts 20%
• Prob. Sets. Maximum Total=50; counts 10%
• Maximum possible total score: 500
2. I rank-order the weighted sums (out of 500) from the largest to smallest.
3. I look for GAPS in the rank-ordered sums and used them as boundaries.
4. I assign grades to each cluster of rank-ordered scores between the gaps.

• Ensures no one is only a few points from getting a higher grade.
• The gaps between grades are usually several points (see below).
• A couple of students in each gap will be treated separately.
• Numbers off slightly due to rounding (makes no difference).
For WINTER 2006 the results for both sections were:
 GRADE: A+ A A- B+ B B- C+ C D,E # getting: 03 28 18 23 14 12 21 15 05 maximum: 494 478 438 421 384 364 345 298 239 minimum: 486 441 426 390 372 352 308 258 133

Note the gaps in scores between grades, except for A/A- (always a problem).
