The ECE 313 Grading Scheme
Grade Distribution Formula:
Scores on homework and examinations will
be weighted as shown below in determining your grade.
To avoid fractions, the Final Exam is worth a maximum of 225 points,
the Hour Exams are worth a maximum of 100 points each, and your
average homework score is normalized to a maximum of 75 points.
Your Grand Total score thus has a maximum of 500 points.
- 15% Homework
- 20% Each Hour Examination
- 45% Final Examination
In computing your average homework score, your lowest
homework score (which could be a 0 for homework turned
in late or not turned in at all) will not be included in the average.
After computing each student's Grand Total score
as the sum of the average homework score,
hour exam scores, and final exam score, we find the mean m and the
standard deviation s of the Grand Total scores.
Letter grades are assigned using cut-offs that
are based roughly
on a mixture of
- objective criteria (85% = A, 70% = B, 55% = C, etc.),
As a rough guideline, we intend to award
- statistical criteria (above-average scores = B or better, etc.).
+ and - grades are typically awarded at the edges of the above cut-offs.
The percentages of A's and B's awarded in ECE 313 are comparable to those
awarded in 300-level required courses in the ECE Department.
- A's to scores greater than min(m+s,425)
- B's to scores in the range min(m,350) to min(m+s,425),
- C's to scores in the range min(m-s,275) to min(m,350)
- D's to scores in the range max(m-2s,225) to min(m-s,275)
- F's to scores below max(m-2s,225)
Trivia regarding grading practices
- The reason for saying rough guideline
is that we reserve the right to make minor adjustments
downwards) to each cut-off
to avoid discriminating between students on the basis of very
small differences in scores. If we must determine a given cut-off where
there is no obvious gap in
scores, we will be favorably influenced by strong performance on the final
- Regardless of your exam performance and the settings of the
cut-offs, however, you will receive the same grade as everyone who has
the same Grand Total score as you, and nobody who has a lower
Grand Total score will receive a higher grade than you.
Request to regrade a problem set
If you think you should have received more points on a particular problem
set you may submit a regrade request. To do so, attach a separate piece of
paper to the front of the homework you'd like regraded, with the heading
REGRADE along with your name, ID, SECTION (9,10,11, or 1), and what problems you
think should be regraded and why, and insert it in the course drop box within one week
after the homework was passed back. Typically graded homeworks are
returned to you in class on Wednesdays, so if you get it into the lock
box by 4pm the same day, it would be returned to you in a week. Or you
could put it in the box for pickup the Wednesday a week later. You might keep
in mind that problem sets account for only 15% of the course score, whereas
each of the two exams during the semester account for 20% each. Thus,
one part of one problem on an exam counts about as much as an entire problem set.
