**is based on 350
points distributed as follows:**

**11 homework **problem sets, worth 10 points
each, due in the lecture on the following Thursday. The lowest score will be
dropped.

**Midterm **on March 7 in the lecture, worth
100 points.

**Final** TBA, 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.
