Basis of Grading

Homework & Attendance	20%
Quizzes	2*25%=50%
Final	30%
Total	100%

Grade Distribution
A	= 88 to 100
B+	= 82 to 87
B	= 76 to 81
C+	= 70 to 75
C	= 65 to 69
D	= 60 to 64
F	= 59 or less
W	= Voluntary withdrawal from course before deadline
I Incomplete may be given in rare instances when the student is unable to attend or otherwise do the course due to illness etc. All of the missed work must be made up during the following semester.

Class Policies
Attendance: Attendance will be taken at the beginning of the class and could be part of homework grade

Examinations: All quizzes and final will be "Closed Book" except the FE Handbook. The quizzes will be given approximately as shown in the schedule. Information regarding exact dates and times will be provided by the instructor one week before each quiz. No make-up quiz will be given. Instead, the weighting for the final examination will be proportionately higher to make up the legitimately missed quizzes. Proper documentation will be required for a legitimately missed midterm.

Homework: Homeworks will be assigned once a week. Homework will be graded and returned to the student during the following week. To obtain full credit, you must submit the work on time and in the proper form. A minimum of 70% of the homework must be submitted to receive a passing grade.

Submissions:

Use 5-square per inch National Computation pad paper ONLY (sold at the NJIT Bookstore). Problems should be done on one side of the 8-1/2 x 11 pad paper.
On the top of each page, in the space provided, print your instructor's name, section, problem number, student's name (LAST, FIRST), date, and page number.
The problems must be presented in numerical order as assigned, with one problem per page. Letters and numbers must be neat, clear and legible.
Draw neat, clear, free body diagrams as required. Use a straight edge or other drawing instruments as needed.
Box in the final answer accompanied by its units. DO NOT HAND IN CLASS NOTES.
Staple the problems in proper numerical order with a single staple in the upper left-hand corner.

Notes:

The NJIT Honor Code will be upheld and any violations will be brought to the immediate attention of the Dean of Students.
Students will be consulted with by the instructor and must agree to any modifications or deviations from the syllabus throughout the course of the semester.
