Final Exam

Policy for + and – grading in class: For each numerical score interval used for a given letter grade (A, B, C or D), the upper third of the interval will be assigned a “+” and the lower third will be assigned a “-“. For example, if a “B” range is considered to in the 80-89 scoring range, a “B-“ will be 80-83, a “B” will be 83-86 and a “B+” will be 86-89.

Policy for late assignments:
For each weekday (exclusive of vacation days) in which an assignment is late, 5% will be subtracted from the total score possible on the assignment.
For example, if an assignment is two days late and the student received an 80% on the assignment, the score adjusted for late penalty will be 72% (i.e. 90% possible * 0.8).
Students with disabilities: Louisiana State University is committed to providing reasonable accommodations for all persons with disabilities. The syllabus is available in alternate formats upon request. If you are seeking classroom accommodations under the Americans with Disabilities Act, you are required to register with the Disability Services (DS). DS is located in 115 Johnston Hall. Phone is 225/ 578-5919. To receive academic accommodations for this class, please obtain the proper DS forms and meet with me at the beginning of the semester.

Code of Student Conduct: Louisiana State University is an interactive community in which students, faculty, and staff together strive to pursue truth, advance learning, and uphold the highest standards of performance in an academic and social environment. It is a community that fosters individual development and the creation of bonds that transcend the time spent within its gates.  To demonstrate my pride in LSU, as a member of its community, I will:

Alcohol Policy (PS-67 Illegal Use of Drugs and Alcohol Misuse): Louisiana State University is committed to maintaining an environment which supports the research, teaching, and service mission of the University. Although the University respects an employee's right to privacy, the illegal use of drugs or alcohol within the University community interferes with the accomplishment of the University's mission.  Louisiana State Law prohibits the consumption, possession, distribution, possession with intent to distribute, or manufacture of drugs described as controlled dangerous substances in the Louisiana Revised Statutes 40:964; and other statutes define the illegal possession and/or use of alcohol.  As such, the Department has reaffirmed the University policy of alcohol-free and drug-free environment on University property at all times and in areas and at times and locations where an assembly of students and faculty would be viewed as representative of LSU (field trips and field camp property as both represent LSU).
