Grading

Grading will be based on the following 5 components, each worth 20% of the grade: (1) class participation, (2) homework, (3) projects, (4) midterm, (5) final exam.

Accommodations for Students with Disabilities

If you have trouble hearing or seeing or have any other disability, please see the instructor to discuss accommodations. Also see the website of the university office of Disability Services for Students (DSS) .

Academic Integrity

For this course you may discuss homework assignments freely with others but you are expected to write up your own work and do your own computer programming. An honor pledge will be required on exams.

The university policy on academic integrity is found in the Code of Student Conduct (http://www.fis.ncsu.edu/ncsulegal/codeof.htm).
