Final 2-5 pm December 14, worth 150 points.

**Course
Policies**

No late homework is accepted. Staple your problem sets! Study groups are encouraged, but homework has to be written down independently.

No makeup exam in this course. If you have to miss an exam for a documented, legitimate reason, please inform me as early in the semester as possible.

You are responsible for lecture notes, any course
material handed out, and attendance in class. The lectures will be conducted as
if you have already read the material and attempted some homework problems. In
this manner, you can focus mainly on those parts of the lectures that cover the
areas of your reading you found difficulty to understand.

If you have any math questions, please feel free to ask me anytime. You can find me after lectures, in office hours, or you can reach me by email.

**Students
with disabilities**

Students with documented disabilities or other special needs who require accommodation must obtain an accommodation letter from Student Disability Services, 385 Garland, (410)516-4720, studentdisabilityservices@jhu.edu. After that, remind the instructor of the specific needs at two weeks prior to each exam; the instructor must be provided with the official letter stating all the needs from Student Disability Services.
