Course Policies
1- Students are strongly encouraged to attend and participate in all class meetings. However, there are no official penalties for class absences.
2- Except for extraordinary circumstances (i.e., authorized medical problems, family emergency, etc.) students are required to take exams at the scheduled times and dates.
3- Homework will be assigned weekly. Homework submitted after the due date will be worth 50% of the point value of the assignment. Homework should be neat and readable, showing calculations and steps for each problem, with clearly marked answers. The student’s name and the problem number should be shown at the top of each sheet.
4- Students are encouraged to work together on homework assignments.
5- Students are expected to conduct themselves with academic integrity. Cheating and plagiarism will not be tolerated on exams and written reports. Any student caught cheating on an exam will receive a 0 (zero) on that exam.
Format: There will be four exams during the semester. The lowest midterm exam will be dropped, therefore no make-up exam will be given.
GRADING: Midterms: Midterm EXAM 1 25%
Midterm EXAM 2 25%
Midterm EXAM 3 25%
Homework 30%
FINAL 20%
