In addition to the Sapling online homework problems, selected problem sets from the text will be assigned, but will not be graded.

 Note: It is extremely important that you work all of the assigned problems.

Active knowledge of the material covered in the problems will ensure that you will be able to work most of the problems on the exams. Also, many of the recitation quizze problems will be taken directly from the asigned problem sets.

No make-up exams or quizes will be given. Missed quizes will result in lost points. If you miss an hour exam, and you have an acceptable excuse, a grade for that exam will be calculated based upon your performance on the other hour exams. Acceptable excuses include unavoidable problems such as illness, injury, or major family issue. You cannot, however, pass the course without passing the final exam, which is comprehensive!

No scratch paper, notes, books, calculators, cell phones, or computers, will be allowed in the exams. You may use molecular models in the exams, but model parts must be contained in a clear zip-lock bag.

Chemistry 3331 follows all CU policies regarding students with disability and religious issues.

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 one week 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 If you have a temporary medical condition or injury, see Temporary Medical Conditions: Injuries, Surgeries, and Illnesses guidelines under Quick Links at Disability Services website and discuss your needs with your professor.

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, a missed hour exam due to religious observances will be treated as an acceptable excuse for missing an exam, and a grade for that exam will be calculated based upon your performance on the other hour exams.

Students and faculty each have responsibility for maintaining an appropriate 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. See policies at University policies - honor code and at University Student Affairs - Student Code
