Examination and Grading

Tests (50%)

There will be 2 tests. These will be announced at least one week in advance.

Final (30%)

There will be a comprehensive final to be worth 30% on Monday 5/4/2015 10:30-12:30 A.M..

Homework and Quizzes (20%)

There will be online homework to be handed in every week.
The online homework will be assigned and completed in Webwork (http://webwork.as.uky.edu/webwork2/uky-ma322-002/). Your username is your LinkBlue ID (use only capital letters), and your password is your student ID number (8 digits).

There may also be some additional written homework. These problems will be assigned after some of the classes and also posted in the web page of the course.
There will be (unannounced) quizzes on some Wednesdays.
Homework and quizzes are equally weighted for the remaining 20% of the grade.

Additional Resources

The university and the department of mathematics offer tutoring without appointment at The Mathskeller . The Study also offers peer tutoring.

Calculators Policy

Calculators are not allowed in quizzes, tests or the final exam.

Code of Conduct

Students should consult the students rights and responsibilities outlined in the Student Code of Conduct. Any offense to the Code of Conduct will result in a grade of "E" for the course and a referral to the Dean of Students.

Excused Absences

University Senate Rule 5.2.4.2 defines the following acceptable reasons for an ”excused absence” from class: Students should notify the instructor of an excused absence prior to the absence whenever possible and complete all work prior to the absence (unless for illness or for the illness or death of a family member).

Students with Disabilities

Students with documented physical‚ learning‚ or temporary disabilities may receive assistance and support from the Disability Resource Center. It is recommended that students contact the Disability Resource Center early to request specific assistance so that the required medical or psychological documentation can be reviewed and reasonable accommodations can be provided from the beginning of class work in order to achieve the greatest benefit to the student.

Changes to this Syllabus

This syllabus can have some changes during the semester. It is responsibility of the students to visit frequently the webpage of the course for up to date information.
