New [3/9/08]: Overall grade and curving. The display now shows your current grade in this class, with curving taken into account. The curve used is an overall curve with cutoffs of 86/72/56/40 percent for A/B/C/D, instead of the standard 90/80/70/60 percent scale. If the semester were to end here, this is the curve that would determine your grade. After each test, I will re-evaluate the curve, and may make small adjustments, depending on the overall score distribution after the test. (Note that the curving is performed on the overall average; no additional curving is done on the individual hw/quiz/exam scores.)

Discrepancies in score display: If you notice any errors in the score display, such as an incorrectly entered or missing quiz or hw score, let me know right away and show me the assignment in question.
Deadlines for reporting score discrepancies: The deadline for reporting errors on assignments prior to, and including, exam1, is Friday March 14. (You must show me the assignment in question.) For future assignments/tests, errors must be reported within one week from the date the test/assignment is returned.
