Final: self-scheduled


There are two midterms and a final. Homeworks consist of problem sets. All homeworks and exams will receive a numerical score. Guidelines of letter grades corresponding to lab/exam score levels will be given during the semester. At the end of the semester, a total score (to which the corresponding final grade is assigned) will be calculated from a weighted average of all scores according to the following weights:

Homeworks: 20%
Midterms: 20% each
Final: 40%
Total: 100%

Homework: You are encouraged to work together on the homework, but you should write up your own solutions. Homework that is more than a week late will not be graded. You are allowed one late homework (late = after the due date, but less than or equal to one week after the due date!). Homeworks are collected once a week, on Tuesdays.

Extensions: Tests may not be taken late without advanced permission. Extensions are usually granted ONLY for family emergencies, infirmary or hospital stays, or similar major crises.

Special Accommodations: Students who think they may need accommodations in this course because of the impact of disability are encouraged to meet with us privately early in the semester. Students should also contact Deb Alder, Coordinator of Accessibility Services, at 610-526-7351 in Guild Hall, as soon as possible, to verify their eligibility for reasonable accommodations. Early contact will help avoid unnecessary inconvenience and delays.

Bryn Mawr College is committed to providing equal access to students with a documented disability.  Students needing academic accommodations for a disability must first register with Access Services.  Students can call 610-526-7516 to make an appointment with the Director of Access Services, Deb Alder, or e-mail her at to begin this confidential process.  Once registered, students should schedule an appointment with the professor as early in the semester as possible to share the verification form and make appropriate arrangements.  Please note that accommodations are not retroactive and require advance notice to implement.  More information can be obtained at the Access Services website (

Any student who has a disability-related need to tape record this class first must speak with the Director of Access Services and to me, the instructor.  Class members need to be aware that this class may be recorded.
