- Grading
- Your grade will be computed from:
- Homework: 15% of final grade (based on the best 10 of 14 assignments);
- Two Midterms: 25% of final grade each;
- Final Exam: 30% of final grade;
- Class conduct: 5% of final grade.
 
- Students will obtain the full 5% for class conduct by default.  Points 
may be deducted for repeatedly being late, repeatedly leaving early, 
sleeping or excessive yawning in class, very poor class attendance, or 
obnoxious behavior.
- In this class, an overall score of 90% or more gets an A; 80% or more 
gets at least a B; 70% or more gets at least a C; and 60% or more gets at 
least a D. You may receive a more generous grade than this, but bear in mind 
that plus and minus grades are not associated with particular numerical 
ranges. Plus grades are rarely used, and the grade of D+ is almost never used.
- Tests
- The two midterms will be held in person, during class on Wednesday, 
February 15 and Wednesday, March 22, 2023.
- The first midterm might be something like this.
- The second midterm might be something like this.
- The final might be something like this.
- The final examination is on Sunday, May 7, 2023 from
7.30pm to 10pm in the usual classroom.
Bring your CU student ID to all of your tests.
- Homework
- 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.
- Students With Disabilities
- If you qualify for accommodations because of a disability, please 
submit your accommodation letter from Disability Services to your faculty 
member in a timely manner so that your needs can be addressed.  Disability 
Services determines accommodations based on documented disabilities in the 
academic environment.  Information on requesting accommodations is located 
on the Disability Services website. Contact Disability Services at 
303-492-8671 or dsinfo@colorado.edu  for further assistance.  If you have 
a temporary medical condition, see Temporary Medical Conditions on the 
Disability Services website.
- 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 weeks 
in advance.  If you miss a midterm exam for any acceptable reason (e.g. 
religious obligation, 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 after
the final has started.
- Classroom Behavior
- Both students and faculty are responsible for maintaining an appropriate 
learning environment in all instructional settings, whether in person, remote 
or online. 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 race, color, 
national origin, sex, pregnancy, age, disability, creed, religion, sexual 
orientation, gender identity, gender expression, veteran status, political
affiliation or political philosophy.  For more information, see the classroom 
behavior policy, the Student Code of Conduct, and the Office of Institutional 
Equity and Compliance.
- Please, no open yawning or sleeping in class!
- CU Boulder recognizes that students' legal information doesn't always 
align with how they identify. Students may update their preferred names and 
pronouns via the student portal; those preferred names and pronouns are 
listed on instructors' class rosters. In the absence of such updates, the 
name that appears on the class roster is the student's legal name.
- Requirements for COVID-19
- As a matter of public health and safety, all members of the CU Boulder 
community and all visitors to campus must follow university, department 
and building requirements and all public health orders in place to reduce 
the risk of spreading infectious disease. CU Boulder currently requires 
COVID-19 vaccination and boosters for all faculty, staff and students. 
Students, faculty and staff must upload proof of vaccination and boosters 
or file for an exemption based on medical, ethical or moral grounds 
through the MyCUHealth portal.
- The CU Boulder campus is currently mask-optional. However, if public health 
conditions change and masks are again required in classrooms, students who 
fail to adhere to masking requirements will be asked to leave class, and 
students who do not leave class when asked or who refuse to comply with 
these requirements will be referred to Student Conduct and Conflict 
Resolution. For more information, see the policy on classroom behavior 
and the Student Code of Conduct. If you require accommodation because a 
disability prevents you from fulfilling these safety measures, please 
follow the steps in the "Accommodation for Disabilities" statement on 
this syllabus.
- If you feel ill and think you might have COVID-19, if you have tested 
positive for COVID-19, or if you are unvaccinated or partially vaccinated 
and have been in close contact with someone who has COVID-19, you should 
stay home and follow the further guidance of the Public Health Office 
(contacttracing@colorado.edu). If you are fully vaccinated and have been 
in close contact with someone who has COVID-19, you do not need to stay 
home; rather, you should self-monitor for symptoms and follow the further 
guidance of the Public Health Office (contacttracing@colorado.edu).
- Honor Code
- All students enrolled in a University of Colorado Boulder course are 
responsible for knowing and adhering to the Honor Code. Violations of the 
Honor Code may include, but are not limited to: plagiarism, cheating, 
fabrication, lying, bribery, threat, unauthorized access to academic 
materials, clicker fraud, submitting the same or similar work in more than 
one course without permission from all course instructors involved, and 
aiding academic dishonesty. Any incident of academic misconduct may be 
reported to Student Conduct & Conflict Resolution (honor@colorado.edu); 
303-492-5550). Students found responsible for violating the Honor Code 
will be assigned resolution outcomes from the Student Conduct & Conflict 
Resolution as well as be subject to academic sanctions from the faculty 
member. Additional information regarding the Honor Code academic integrity 
policy can be found on the Honor Code website.
- Sexual Misconduct, Discrimination, Harassment and/or Related Retaliation
- CU Boulder is committed to fostering an inclusive and welcoming learning, 
working, and living environment. University policy prohibits sexual 
misconduct (harassment, exploitation, and assault), intimate partner 
violence (dating or domestic violence), stalking, protected-class 
discrimination and harassment, and related retaliation by or against members 
of our community on- and off-campus. These behaviors harm individuals and 
our community. The Office of Institutional Equity and Compliance (OIEC) 
addresses these policies, and individuals who believe they have been 
subjected to misconduct can contact OIEC at 303-492-2127 or email 
cureport@colorado.edu. Information about university policies, reporting 
options, and support resources can be found on the OIEC website.
- Please know that faculty and graduate instructors have a responsibility 
to inform OIEC when they are made aware of any issues related to these 
policies regardless of when or where they occurred to ensure that 
individuals impacted receive information about their rights, support 
resources, and resolution options. To learn more about reporting and 
support options for a variety of concerns, visit 
Don't Ignore It.
- Religious Holidays
- Campus policy regarding religious observances requires that faculty 
make every 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 inform your professor of any
conflict as soon as possible.
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.
- See the campus policy regarding religious observances for full details.
