Exams

The lowest of three hour-exam grades will be dropped. Dates of hour exams are tentative; any change will be announced at least one week in advance of the original test date or modified test date, whichever is earlier. Students should be prepared to take up to 3 unannounced surprise Stealth Quizzes (15 minutes) during the semester; the scores will be included in the total for exams on a time-prorated basis.

Any request for regrading of a test problem should be made within one week (by 5:00 PM) of the day graded tests are returned, by the following procedure. On a separate sheet, write your name and a clear explanation --- with specific reference to the point scheme distributed with the solution --- of why you should receive more points on the problem in question. Please do not make any marks on the test booklet itself. Turn in this sheet to me together with the exam booklet. Under no circumstances can a regrade be considered if the test booklet has been marked or altered in any way from what was handed back to the student.

Homework

Homework sets will be usually assigned on the Monday of each week for collection on the following Monday (with the exception of some longer computer projects).

To obtain the learning benefit of student interactions in a documentable way, the class will be subdivided into homework groups of 2 or 3 students - to be finalized and recorded during the first week for the entire semester. Each group will submit a team homework solution, on which all members will receive the same score. Students are on their honor to

Absolutely avoid any collaboration or sharing of information whatsoever between different groups.
Contribute as equally as possible to the team homework process and not attempt to be carried by the efforts of the rest of the group;

These two stipulations are of the utmost seriousness: they are on the same level as the rules of professional and ethical conduct during classroom examinations. Grading will emphasize problems carried through to successful completion, with substantially less credit given for unfinished solutions.
