Tests and Exam:
No
books or notes are permitted. All cell
phones must be turned off and kept in backpacks during any test or exam. No
make-up exams will be given unless a compelling documented excuse is presented.
Your lowest test score will be replaced by your final exam score if it is
higher. You are taking this course under the guideline of LSU Code of Student Conduct . The University
has clear policies requiring academic honesty.
If there is clear evidence that a student has committed fraud to advance
his/her academic status (e.g. cheating on a test or exam), your instructor will
report to the Office of the Dean of Students.
Homework:
Homework will be assigned weekly
on this course homepage. They will not be collected but it is strongly recommended that you
finish your homework on time. The questions in the quizzes, midterm exams and the final
exam will be similar to those homework problems. Students are recommended to
work in groups on the homework, but each student should write up his/her own
solutions on paper.
Quizzes:
There will be weekly
quizzes. Each quiz is about 15 minutes long, largely consists of problems
chosen from homework assignments. Two lowest quiz scores will be dropped in the
end. No make-up quizzes will be given unless a compelling documented excuse
is presented.
Attendance and class
preparation:
Regular
attendance is required for this course. You should make every effort not to
miss any class and complete all the homework in a timely fashion. It is your
responsibility to catch up with missed lectures. You are responsible for the
announcements made in class.
General Advice:
The
amount of material to be covered in this course is substantial. To do well in
this class, students are recommended to spend at least two hour each day on
reading the sections covered, reviewing notes and working assigned homework.
