If you have any questions or concerns, please ask in
lecture, during office hours, or on Ed.
Graded Work

Guided problem sets (GPS) are autograded on PrairieLearn.

Written homeworks are graded by the entire course staff, directly
within Gradescope. Each numbered
problem is graded by several CAs, under the supervision of one
TA, using a common detailed rubric developed within
Gradescope. All numbered homework problems are worth the same
amount. Under normal circumstances, all homework should be graded
within two weeks of submission.

Exams are graded by the instructors and graduate TAs.
Graded exams will be available via gradescope. Under normal
circumstances, all exams should graded within two weeks.
Regrade Requests
 Regrade period for homeworks/exams is one
week after the grade is available. Homework and exam regrades are to
be requested within Gradescope. Late regrade requests will be ignored.
 Please check that your grades are tabulated and recorded
correctly. If you notice a mistake, please use gradescope
to ask for a regrade.
 If you do not understand your grade on a homework or exam
problem, you may discuss your grade with one of the TAs or
instructors during office hours. After that discussion, if
you still believe that your work has been graded incorrectly,
please request a regrade.

All regrade requests must include a brief written
justification for the request. Good justifications
include the following:
 My answer agrees with the posted solution, but I still
lost points.
 I lost 4 points for an incorrect time analysis, but
the rubric says that's only worth 2 points.
 You took off points for missing the base case, but it's
right here (right here!).
 My answer is correct, even though it does not match the
posted solution. (This happens more frequently if your
answer is not even remotely similar to the "standard"
solution.)
 There is no explanation for my grade.
 The official solution is incorrect; here's a counterexample.
Regrade requests with poor or missing justifications will be
denied.
 We can only grade what you actually
submitted. You
cannot get a higher grade by explaining what you meant, either
in person or in writing; your original submission must stand on
its own.

If you submit a regrade request, we will regrade the
submitted problem from scratch.
Your grade may go down. Regrade requests
will initially be handled by a TA; if disputes persist, they will
eventually be handled by the instructors.

We will readily admit, apologize for, and correct our mistakes
if you have been graded unfairly. However, please remember
that "unfairly" means your grade is inconsistent with the
published grading rubric, or that you were graded more harshly
than other students, not just that you think the
rubric itself is too harsh. Please also keep in mind that each percentage point
of a homework is worth approximately 0.01% of your final
course grade. Don't fight for each point like your life
depends on it!
Final Course Grades
We will determine final course grades as follows.
 We compute the raw total from your homework and exam scores.
Course work is weighted as follows.
 We reserve the right to give any student meeting at least one of
the following conditions an automatic F:
 Raw total below 33%
 Raw exam average below 25%
 Submitted less than half of the 33 homework problems (unless there is an overriding excuse).
These are not the only ways to fail!
 We determine your fixed letter grade from the raw total according to the following cutoffs:
Min  Max  Grade 
95  100  A+ 
90  95  A 
85  90  A 
80  85  B+ 
75  80  B 
70  75  B 
65  70  C+ 
60  65  C 
55  60  C 
50  55  D+ 
45  50  D 
40  45  D 
0  40  F 
 Alternatively, we determine your curved letter grade from the raw total.
The mean is a borderline B/C+, and each standard
deviation is worth one full letter grade. For example, the B+/B
cutoff is 2/3 standard deviations above the mean, and the D/D cutoff
is 5/3 standard deviations below the mean. We may decide to exclude
certain outliers from the cutoff computation, to avoid unfairly
skewing the curve.
 Your actual letter grade is either your fixed letter grade or your curved letter grade, whichever is higher.
 We reserve the right to adjust grades upwards at the instructors' whim.
