- Highest scores: 50 (3)
- Lowest score: 8
Grading Information
Curving: The raw score was converted to a curved score
on a 100/90/80/70/60 percent scale as follows:
- 42/50 - > 45/50 = 90% (cutoff for A);
- 34/50 - > 40/50 = 80% (cutoff for B);
- 25/50 - > 35/50 = 70% (cutoff for C);
- 15/50 - > 30/50 = 60% (cutoff for D);
Intermediate scores were converted by interpolating between the above data
points. (This was done by the computer grading program.)
Letter grades: The curved scores correspond to letter grades with
plusses and minuses as follows:
- 97% - 100%: A+
- 94% - 96%: A
- 90% - 93%; A-
- 87% - 89%: B+
- 84% - 86%: B
- etc.
Note: This letter grade correspondence is for your
information only. The grading program uses the more precise
numerical scores, not the letter grades,
for all internal computations.
Accessing your scores
To access your current scores, go to this URL:
https://www-s.math.uiuc.edu/bluestem/grades.cgi
(There is a link to this site on the main page for this class.)
You will be asked to login with your Net-ID and password; this is the same
login/password combination that you'd use when you register online.
At the end of the score display, an "average" is shown, expressed both
as a percentage and as a letter grade (with plusses and minuses).
This average represents your current (i.e., pre-final) grade.
It was computed by averaging the curved homework grades (with the
lowest homework score dropped - the drop score is indicated by a double
asterisk (**)), and the exam grades. The average was weighted
appropriately to take into account the relative weights of these
components towards the
course grade: 20 % for hw, 45 % for hour exams. The remaining 35 % come
from the final exam. Your course grade will be the grade shown as
"average" in the grade display after the final exam scores have been
entered and a curve for these scores has been set.
Since each grade component was curved individually, no additional
curving will be done at this stage.
You can work out what you need on the final to achieve a particular
score: If p is your prefinal score, expressed as a percentage,
(e.g., p = 88 % = 88/100) and f your final score after curving,
then your overall
score will be 0.65p + 0.35f. For example, p=88 and f=94 results in an
overall score of 0.65 x 88 + 0.35 x 94 = 90.1 which translates into an
A-.
