2. Grading Scale
Since class average usually is above 70, there may not be any curving in this course. If not
curved, your grade will be assigned to your overall course average as given below:
90-100: A
80-89.9: B 70-79.9: C
60-69.9: D
Below 60: F
I. Exams
Exams shall be open notebook and textbook. Small size blue books shall be supplied for the
exams. You may be seated in the exams. Seating charts shall be available on the door of the class
room before the exam if I decide to seat you.
J. Make-up Exams
No make-up exam shall be given unless it is absolutely necessary. You must contact me and
get approval to take the make-up exam before the regular exam starts. Only one make-up
exam shall be given for all missed exams on the last day of the class. Test shall cover all topics
included in all previous exams and may be more difficult than regular exams.
K. Home Work
Homework is for you to do it at home. You must not solve homework problems together with
anyone else since end result may be considered to be cheating. Due hour for the homework sets
is on the due date, before class starts. Ten points out of one hundred points shall be deducted for
each day of late submission. Holidays and weekends shall not be counted for lateness. No
homework sets shall be accepted and graded after they are returned back to class or after five
working days of the due date, whichever comes first. Homework due on the weeks of exams
must be turned in on time. Last homework set must be turned in, on or earlier than the final exam
day and time. Exam re-do homework sets and some other homework sets may be graded based
on correct answers only: You may receive no credit if answer is wrong, full credit if answer is
correct. A cover page should be attached to each homework set and laboratory report. A copy of
cover page is given at the end of syllabus. If you enter any information wrong or leave out some
information on the cover page, penalty will be 5 points.
If I am left behind in teaching and I did not change the due date of some problems on the set, you
are required to submit your homework on time. Please read the material that I did not cover and
submit your homework on time.
Up to 20% may be deducted if units are not used or incorrectly used. Up to two points out of ten
may be deducted if homework sets are not neatly and clearly presented. Submit your homework
sets directly to me, just before the class or toss it under my door any time. Homework sets shall
be returned to you in about one week's time. If you are late to a class and there is homework
due, your homework is also late.
4
L. Attendance
Attendance is very important in my courses since I tend to ask questions in exams on the topics I
stress on. I shall take attendance from time to time (about once a week). Let me know if you
have any serious reasons not to attend a class. Percentage of classes you miss will be calculated
using "number of classes missed divided by the number of attendances taken". Two late-comings
to a class will count as one class-day missed. You are late if you come-in to the classroom
after class start time and you see me inside.
M. Policy on W-Grades
Due to very strong correlation between the Midterm grade and the course grade, I am
recommending you to drop the course if you end up receiving an "F" as your Midterm grade and
you do not have very good reason(s) for failing through the end of the midterm exam. "W" grade
can only be received if you drop the course before the end of Withdrawal deadline. No grade
will appear on your record if you drop the course before the end of Drop deadline.
N. Policy on Incomplete Grades
No incomplete grade will be passed unless there is an emergency on your part which will not let
you complete the course. In order to receive an incomplete grade you must be passing the course
at the time of the emergency and must have completed major portion of the course.
O. Disability Statement
Students capable of success, regardless of their disabilities are admitted to the university. The
faculty and staff of the University of Maryland Eastern Shore work cooperatively to assist their
students in achieving their educational goals. Moreover, students with disabilities are
accommodated in accordance with both federal and state laws. To receive special
accommodations for a disability, the student must register with Student Disability Services
before any accommodations can be granted. At the time of registering for disability services,
please bring documentation to support your claimed disability. The documentation must be
within three years and provided by a licensed professional with expertise in the special disability
area. If you have questions about disability services or accommodations, please contact Dr.
Dorling Joseph at (410) 621-3446. The Student Disability Services office is located in the
Student Services Center (SSC), Suite 2169.
P. Cheating
Any cheating shall be penalized severely. Severeness of penalty shall depend on how much
evidence is collected for cheating. I want to make it sure that only those who take the time and
do their work will receive the grade. Any student who CHEATs will receive, as a minimum, zero
in the exam or in the homework.
Depending on the severity of cheating, student may be reported to campus academic authorities
for proper penalty. If cheating in any homework set or in any laboratory report is repeated, your
homework privileges may be suspended. In this situation weight of the homework sets shall be
moved to the exams. Laboratory reports and any home assignments are considered to be
5
homework. To avoid any possible cheating problems, you must not do homework or home
assignments, or write laboratory reports with any one else.
Not limited to, but, any of the following constitute cheating:
1. Giving or receiving any written information about solution of any home assignment,
2. Transcribing solution of an assignment,
3. Using solutions of home assignments which were not done by the user (like last year's
homework solutions done by someone else),
4. Giving or receiving any information or materials during exams, including printed materials,
pencils, calculators, erasers, etc.,
5. Talking in the exams, even if it is not related with the exam,
6. Looking over someone else's exam paper during exams,
7. Using any materials that are not allowed in an exam,
8. Any other acts considered to be cheating, plagiarism or falsification by the University
regulations. Some of these acts are given in the university catalog. It is your responsibility to
know and understand these acts.
To deter and prevent cheating during exams, open or hidden video and/or tape recorders may be
used. You will not be told whether or not the exam is being recorded and/or taped.
Q. Cell Phone Use
Cell phone use is not allowed in class rooms. You must turn your cell phone off unless you are
expecting an emergency call. You need to get my permission to leave the phone on (vibrate
only). One point shall be deducted from your overall average for each disturbing call you receive
or each time I see you playing with your phone.
R. UMES Zero Tolerance Policy
The University of Maryland Eastern Shore maintains and strictly enforces a policy of zero
tolerance with regards to fighting, the use, possession and/or distribution of illicit drugs, and the
possession of dangerous weapons, firearms, and explosives. If a student is found guilty of using,
possessing, selling or distributing illegal drugs; initiating a fight, or using any object (weapon)
with the intent to cause harm, the minimum sanction will be suspension from the University for
one (1) academic semester, and where appropriate will be referred to local policing authorities
for criminal prosecution. Suspension from the University for a violation of the zero tolerance
policy will result in the cancellation of the accused student’s housing contract, lost of tuition
and fees, grades attempted, and denial of a housing contract in the future. If a student is found
guilty of drug distribution or the possession of dangerous weapons, firearms, or explosives, the
maximum sanction may result in expulsion from the University.

STANDARDS FOR HOMEWORK, PROJECTS AND TESTS
Effective communication is an important part of engineering. A correct technical result that is
poorly communicated is often no better than one which is incorrect. To emphasize this fact,
consideration of effective communication will be given in grading homework, projects and tests.
Anything which seriously detracts from ease of understanding of your work can result in a loss of
points. Illegibility will be considered as serious fault for which points will be deducted.
Homework and Project Standards
Your written homework and projects will be judged according to a recommended standard. Each
Homework problem will be treated as a formal engineering assignment. Give table or/and figure
numbers when data is taken from them. Interpolate approximately on tables unless exact
interpolation is required by the problem statement. Write as clearly and as explicitly as possible,
results and solutions shall not be guessed. Use only one 8.5 x 11 in size paper, and put your initials
on each page. A title page should be added to each assignment. Title page should contain:
(a) Course number and name,
(b) Homework set no,
(c) Problems submitted.
(d) Due date,
(e) Submission date,
(f) Days late,
(g) Your full name, and
(h) Grade.
Staple your assignment at the left hand upper corner and DO NOT FOLD IT. You may use files
for the projects. A sample title page is enclosed you may copy and use it.
The solution for each problem should contain:
(a). Problem statement,
(b). Sketch and/or diagram,
(c). Analysis and results (if lengthy, summarize results in body of report, with details
in appendix),
(d). Discussion and conclusions when applicable.
For table and figure notations follow the same form given for the figures and tables in your textbook
(i.e. table number and title at top for tables, figure number and title at bottom for figures).
7
Test Standards
No specific form standard can be given for tests since they may vary greatly and the student is under
time pressure. For this reason it may be necessary, also, to overlook minor errors in spelling,
punctuation, or grammar. It is to your own benefit, however, to communicate your knowledge to the
grader as well as you can. With this in mind, you should practice effective communication
techniques during tests.
Occasionally points may be deducted for unnecessarily poor communication. To avoid this, you
should follow the following rules:
(a). Small size blue books shall be supplied
(b). Put problem solutions in numerical order. Put problem numbers on every other or three pages
(depending on the number of problems in the test) of your blue book. Start with the first one and go
on in increasing order. Now you are ready to start answering any problem you like. Write the
answers in the reserved section of your blue book for the problem you have started.
(c). Bring the supplemental materials (tables, charts etc.) distributed in the class. No charts,
tables, equations etc. shall be supplied during exams.
(d). Always use more detailed charts and tables. Most of the time distributed charts and tables are
more detailed.
(e). Write your name and course name on the blue book. If there are any loose sheets, put your
names on each of them,
(f). Write clearly and legibly, no guessing is allowed when grading the exams,
(g). State important assumptions clearly,
(h). Flag important results by underlining or boxing
(i). If the solutions should be excluded from grading, cross it out clearly and completely,
(j). Give only one solution. Otherwise, first solution shall be accepted as the answer to the
question.
(k). Use the closest entry on the tables, do not interpolate unless it asked to interpolate,
(l). Be as accurate as possible when reading charts.
