Here is the distribution of final exam scores. There was no significant difference between the grade distributions of the regular exam and the conflict exam, and there were no outliers above 95% or below 25%.

Please contact Jeff after break if you have any questions or concerns about your grade.
All students are welcome to take the conflict exam, even if you do not have an official conflict, but space is limited. If we cannot accommodate everyone who wants to take the conflict exam, students with official conflicts will have priority, followed by other students in order of registration.
If you're interested in taking this class (and being a guinea pig for one more semester), please register soon!
Here is the distribution of scores. The statistics and letter-grade cutoffs exclude outliers above 95% and below 25%. Conflict exams are included in the overall statistics and letter-grade cutoffs, but not in the statistics for individual problems. (There was no significant difference between overall grade distributions for the two exams.)

Here is the distribution of scores. The statistics and letter-grade cutoffs exclude outliers above 95% and below 25%, but include scores from the conflict exam (because they did not significantly change the outcome).
Please keep in mind that these letter grades are extremely rough predictions, based on only 20% of your overall coursework. Based on past experience (in CS 473), we expect most students' final course grades to be within one letter grade of these estimates, but differences of up to a full letter grade (in either direction) are fairly common, and differences of up to two letter grades (in either direction) are are still possible.

If you are interested in taking this class this semester: This is only the second pilot offering of CS 374. We have deliberately limited registration to 100 CS and CE majors who filled out an interest survey in April 2014 and who have taken CS 225 but not CS 373.
If you are interested in taking this class in the future: CS 374 will be offered at full scale, with an expected registration limit of 400 students per semester, starting in Spring 2015. CS and CE majors will have first priority, but we hope that there will also be room for students with other majors.
If you are a graduate student: You should take CS 573.

En un mot les calculs sont impracticables. |
