- Update: Midterm 2
- Despite what was said earlier, midterm 2 will be a take-home
exam. You will be allowed to use notes and books, but you will not be allowed
to use other people or the internet as resources. The exam will cover the
expected material and will be of the expected level of difficulty, but the
questions will be more detailed or longer than for an in-class exam. There will
be an online class as usual on March 18, and the exam will take place after
- The second midterm might be something like
- Update: Final
Despite what was said earlier, the final will be a take-home exam. The exam
will be distributed by email before 9am on the "reading day", Friday,
May 1. I will be available at 9am that day to discuss the exam, and to
answer questions about it.
The final will be due at 4pm on Tuesday, May 5. As usual, the final
should be submitted by email to me, as a single pdf with a helpful filename.

- Homework is due at the beginning of class.
Some, but not all of the problems will be graded. Justify all your answers.
You should assume that late work will not be graded.
- Update: Homework
- Online homework must be submitted by email as a single pdf. Please give your
file a useful name: Chris_HW10.pdf is helpful, but
myhomework.pdf is not.
- Students With Disabilities
- If you qualify for accommodations because of a disability, please submit to
your professor a letter from Disability Services in a timely manner (for
exam accommodations provide your letter at least two classes prior to the exam)
so that your needs can be addressed. Disability Services determines
accommodations based on documented disabilities. Contact Disability Services
at 303-492-8671 or by e-mail at dsinfo [AT] colorado.edu.
- If you have a temporary
medical condition or injury, see Temporary Medical Conditions: Injuries,
Surgeries, and Illnesses guidelines under Quick Links at the Disability Services
website and discuss your needs with your professor.
- Missed Exams
- If you know that you are going to miss an exam or cannot take the final
exam at the scheduled time, please notify your instructor at least two classes
If you miss a midterm exam for any acceptable reason (e.g.
religious obligation, documented illness), that midterm exam score will be
replaced by an estimated score based on your performance on the other midterm.
If you miss both exams for acceptable reasons, your midterm scores will be
replaced by estimated scores based on your performance on the final.
If you miss the final exam and have not rescheduled it in
advance, you will score zero on the final or receive an incomplete in the
course, depending on the circumstances.
You may not reschedule a final exam after the exam has started.
- In order to be excused from an exam for medical reasons, you must either
produce a note from a doctor, or you must obtain prior permission from the
instructor to miss the exam. Self-diagnosis and self-medication are not
acceptable for this purpose.
- Religious Obligations
- Campus policy regarding religious observances requires that faculty
effort to deal reasonably and fairly with all students who, because of
religious obligations, have conflicts with scheduled exams, assignments or
required attendance. In this class, you should notify your instructor of
any conflict immediately.
- In the case of conflicts with exams, if you do not inform your instructor
of the conflict at least two classes in advance of the exam,
you must provide documentary evidence of the religious obligation.
- Student Classroom and Course-Related Behavior
- Students and faculty each have responsibility for maintaining an
learning environment. Those who fail to adhere to such behavioral standards may
be subject to discipline. Professional courtesy and sensitivity are especially
important with respect to individuals and topics dealing with differences of
race, color, culture, religion, creed, politics, veteran's status, sexual
orientation, gender, gender identity and gender expression, age, disability,
and nationalities. Class rosters are provided to the instructor with the
student's legal name. I will gladly honor your request to address you by an
alternate name or gender pronoun. Please advise me of this preference early in
the semester so that I may make appropriate changes to my records.
Please, no open yawning or sleeping in class!
