General Information

Grading

The course grade will be based upon on weekly homework (50 points), two midterms (75 + 125 points) and a final exam (200 points).

Plagiarism, collusion, or other violations of the Academic Honor Principle, after consultation, will be referred to the The Committee on Standards.

Exams

There will be one in-class "midterm examination" and an in-class final examination. These will not be during the regular class times.

Do not make plans to leave Hanover before the end of the final exam week . The exams will not be given earlier to accommodate your travel plans. The exams are scheduled as follows:

Here is a sample of past exams from other Instructors.

If you have a legitimate conflict with the scheduled exam time you may take the exam from 7 to 9 pm on the same day, provided you receive written permission from your instructor prior to the day of the exam.

Homework

Written homework will be assigned weekly and will be posted on the homework page. It will be due each Wednesday, and is to be turned into the homework boxes outside of Kemeny 108 by 3:30 p.m; no late homework will be accepted. Homework will typically cover the material up through the previous Friday.

No late homework will be accepted. However, your lowest homework score will be dropped.

Please follow the homework submission guidelines.

Cooperation on homework is permitted (and encouraged), but if you work together, do not take any paper away with you--in other words, you can share your thoughts (say on a blackboard), but you have to walk away with only your understanding. In particular, you must write the solution up on your own. Please acknowledge any cooperative work at the end of each assignment.

Honor Principle

On Exams: Any student giving or receiving assistance during an examination or quiz violates the Academic Honor Principle.

On Homework: Collaboration is permitted and even encouraged, but obviously it is a violation of the honor code for someone to provide the answers for you. However, assistance of any kind should be properly acknowledged.

Tutorials

Our graduate teaching assistants will run tutorials, Sunday, Tuesday, and Thursday nights from 7-9pm in Kemeny 108, focusing on working through problems. Please note that the students in the previous years found these tutorials to be very helpful! Please bring questions you are stuck on! Your TA is Yunxiang Wan.
