Homework Homework sets will be assigned on Thursdays and due the following Thursday, unless specified otherwise by the instructor. Late homework are not accepted unless prior approval is given.
Exams Students are expected to take the examinations when offered. A makeup examination will be given for students who miss a regular examination with an excused absence and prior approval by the instructor. Students who for unexcused reasons miss examinations will be given zero credit for those examinations. In class exams will either be closed book or open book and will be specified during the class period immediately preceding the exam. For closed book exams course material must be purged from the memory of calculators prior to the exam. Requests to re-grade any part of an exam must be submitted to the instructor within 48 hours after receiving the graded exam with a written justification specifying why you think your exam or exam question should be re-graded. Neatness and clarity of presentation will be considered when examinations and homework assignments are graded. Americans with Disabilities Act (ADA) Policy Statement The Americans with Disabilities Act (ADA) is a federal antidiscrimination statute that provides comprehensive civil rights protection for persons with disabilities. Among other things, this legislation requires that all students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of their disabilities. If you believe you have a disability requiring an accommodation, please contact Disability Services, in Cain Hall, Room B118, or call 845-1637.

Aggie Honor Code “An Aggie does not lie, cheat, or steal or tolerate those who do.” Upon accepting admission to Texas A&M University, a student immediately assumes a commitment to uphold the Honor Code, to accept responsibility for learning and to follow the philosophy and rules of the Honor System. Students will be required to state their commitment on examinations, research papers, and other academic work. Ignorance of the rules does not exclude any member of the Texas A&M University community from the requirement or the processes of the Honor System. For additional information please visit. www.tamu.edu/aggiehonor/. On all course work, assignments, and examinations at Texas A&M University, the following Honor Pledge shall be preprinted and signed by the student: “On my honor, as an Aggie, I have neither given nor received unauthorized aid on this academic work.”
