There will be two "midterm examinations" and a final examination. The exams are scheduled as follows:

Exam 1 April 21, 2016 6:00-8:00PM Wilder 111
Exam 2 May 12, 2016 6:00-8:00PM Filene Auditorium (Moore Hall)
Final Exam June 2, 2016 11:30 AM - 2:30 PM Moore B03

Homework Policy


The course grade will be based upon the scores on the midterm exam, homework, quizzes, and the final exam as follows:

Assignment Number Percentage of the Grade
Midterm Exams 2 25% each
Final Exam 1 35%
Homework 8(-1) 15%

The lowest homework grade will be dropped at the end of the term.

The Honor Principle

Cooperation on exams is, obviously, not permitted.

Cooperation on homework is permitted (and encouraged), but you are responsible for writing up your own solutions. Simply copying someone else's solutions is a violation of the honor code.


Our graduate teaching assistant will run tutorials, Sunday, Tuesday, and Thursday nights from 7-9pm in 006 Kemeny, 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 Melanie Dennis.

Disabilities, Religious Observance, Etc

We encourage any students with disabilities, including "invisible" disabilities such as chronic diseases and learning disabilities, to discuss appropriate accommodations with your instructor, which might help you with this class, either after class or during office hours. Dartmouth College has an active program to help students with disabilities, and we are happy to do whatever we can to help out, as appropriate.

Any student with a documented disability requiring academic adjustments or accommodations is requested to speak with their instructor by the end of the second week of the term. All discussions will remain confidential, although the Student Accessibility Services may be consulted to verify the documentation of the disability and advise on an appropriate response to the need. It is important, however, that you talk to us soon, so that we can make whatever arrangements might be needed in a timely fashion.

Some students may wish to take part in religious observances that occur during this academic term. If you have a religious observance that conflicts with your participation in the course, please meet with your instructor before the end of the second week of the term to discuss appropriate accommodations.
