Grading Standards
Here are the percentage cutoffs that I use for determining letter
grades.
Average | CIS 100 | Major Course |
93-100 | A | A |
90-93 | A- | A- |
87-90 | B+ | B+ |
83-87 | B | B |
80-83 | B- | B- |
77-80 | C+ | C+ |
73-77 | C | C |
70-73 | C- | C |
67-70 | D+ | D+ |
63-67 | D | D |
60-73 | D- | D- |
below 60 | F |
Percentage grades are rounded off to the nearest whole number, and
if you are just on the edge, you will receive the higher letter
grade.
Curving
I don't like grading on a curve, so don't request it. First of all,
the classic curve requires me to give as many Fs as As, as many Ds as
Bs, and the bulk of the grades will be Cs. Second, the philosophy of
curving says that there is no absolute standard of performance, but
that as long as you do better than your classmates, you deserve a good
grade, even if you have not mastered the material. Instead, I believe
that a grade of A should mean excellent performance and complete
mastery of the material. Sometimes no one in the class deserves that
grade. Sometimes everyone does. Grading on a curve says that about 3
percent do, regardless of their absolute performance.
Class-wide Adjustments
I would prefer to stick with this grading policy under all
circumstances, but it sometimes happens that a class does much worse
than expected. Rather than fail a large number of students, I may
slide all the grades up by the same number of points. However, you
should note that this is an undeserved mercy, and you should neither
expect it nor request it.
Mistakes
I try hard to be consistent and fair, but I am not infallible. If you
think that I (or the teaching assistant) have made a mistake in
grading a homework, program, test, or whatever, come and discuss it
with me. You must logically argue that it is a mistake or is
inconsistent, and not just wheedle for extra points. I reserve the
right to re-grade your entire test if I feel you are just wheedling.
Such discussions must be done in private in my office. I don't
discuss individual grades during class, even if we are going over a
test or anything else I have just handed back.
Graded Work
You should keep all your graded work until after the semester is over
and you have received your final grade. It sometimes happens that I
mis-record one of a student's grades, and if you have kept your graded
work, such clerical errors can be fixed. Please do not count on my
memory ("Don't you remember that on assignment 2, I got a ..."); keep
your graded work.
Interim Performance
Students often ask how they are doing during the semester. In a way,
this question puzzles me: you know what the grading standard is, you
know the grades you've gotten so far, so you can calculate your
current grade yourself. If you don't know how to calculate your
grade, read this.
Since the Fall of 1998, I have been using an online database for
recording your grades. This database has a web interface, so you
can check your grades over the web. Since you can check your grades
at any time, I expect you to keep track of how you're doing. Be
sure to read the directions.
Extra Credit
Students who are doing badly often ask me for an extra credit
assignment. I would rather not give additional work to someone who is
already behind. Furthermore, I feel it's important to be fair by
allowing all students access to the extra credit, so I really have to
make up an additional assignment for the whole class. I would rather
not do that. The way to improve your grade is to study hard and do
better on the upcoming tests and assignments.
