If you are a student with a disability and believe you will need academic accommodation, you must formally request accommodation from Meg Hegener, Coordinator of Student Access Services. You will also need to provide documentation which verifies the existence of a disability and supports your request. For further information, please call 580-8150 or stop by the office of Student Academic Services in Starbuck Center.

A word on Title IX

Skidmore College considers sexual and gender-based misconduct to be one of the most serious violations of the values and standards of the College. Unwelcome sexual contact of any form is a violation of a student’s personal integrity and their right to a safe environment and therefore violates Skidmore’s values. Sexual and gender-based misconduct is also prohibited by federal regulations. Skidmore College faculty are committed to supporting our students and upholding gender equity laws as outlined by Title IX. If a student chooses to confide in a member of Skidmore’s faculty or staff regarding an issue of sexual or gender-based misconduct, that faculty or staff member is obligated to tell Skidmore’s Title IX Coordinator or Title IX Deputy Coordinator. The Title IX Coordinator or Deputy Coordinator will assist the student in connecting with all possible resources for support and reporting both on and off campus. Identities and details will be shared only with those who need to know to support the student and to address the situation through the college’s processes. If the student wishes to confide in a confidential resource, The Counseling Center Staff, Health Services, and Victim Advocates are all options available.


Homework will make up 20% of the overall course grade. Your lowest homework score will not be counted in the final tabulation. The purpose for this is to give you an opportunity to miss an assignment in an emergency without having to notify me or explain your reasoning. I highly recommend saving your allowed missed assignment for an instance in which you are truly unable to submit it.

Assignments are due by 17:00 on the specified days. You may hand in homework before or after class, but please do not interrupt lecture to do so. Work may also be turned in to my mailbox in the math office hallway any time prior to the deadline. Late work will not be accepted for any reason.

To make life easier on the grader, you must ensure that your name is written clearly on the front of your homework, that your pages are stapled securely together and that all spiral binding scraps are removed from the page edges.
