Weekly Graded Homework Assignments:
▪ http://m.njit.edu/~jobech/fall09/hmwk222.html
Homework and Quiz Policy:
Homework Assignments chosen from the text are
listed below. Students are required to work through these problems after each lecture in order to gain a better understanding of the course material.
Weekly quizzes will be based on these exercises.
Additional
homework assignments will be collected and graded each week. They are to be handed in at the beginning of the first lecture each week,
starting with Week 2.
Attendance: Attendance at all classes will be recorded and is mandatory. Please make sure you read and fully understand the Department’s Attendance Policy. This policy will be strictly enforced.
MATLAB: MATLAB is a mathematical software program that is used throughout the science and engineering curricula. Several MATLAB assignments will be given out. These assignments have been designed to help you learn how to use this software in order to visualize many of the concepts taught in class.
Exams: All sections of Math 222 will take three common midterm exams during the semester and one common final exam during the final exam week. Midterm exams are held on Wednesdays on the following days:
|
Exam 1: |
September 30, 2009 |
|
Exam 2: |
October 28, 2009 |
|
Exam 3: |
December 2, 2009 |
|
Final Exam Week: |
December 11-17, 2009 |
Day sections will have common examinations on the above listed dates from 4:15pm to 5:40pm and evening sections from 5:45pm to 7:10pm. A comprehensive final examination will be given at the end of the semester. The date for this final examination will be announced at the end of the semester.
Make sure you read and fully understand the department's
Examination Policy.
This policy will be
strictly enforced.
Makeup Exam Policy: There will be No make-up EXAMS during the semester. In the event the Final Exam is not taken, under rare circumstances where the student has a legitimate reason for missing the final exam, a makeup exam will be administered by the math department. In any case the student must notify the Math Department Office and the Instructor that the exam will be missed and present written verifiable proof of the reason for missing the exam, e.g., a doctors note, police report, court notice, etc., clearly stating the date AND time of the mitigating problem.
Further Assistance: For further questions, students should contact their Instructor. All Instructors have regular office hours during the week. These office hours are listed at the link above by clicking on the Instructor’s name. Teaching Assistants are also available in the math learning center.
Cellular Phones: All cellular phones and beepers must be switched off during all class times.
