Course Policies

(1) Prerequisites: A grade of 'C' or better in MAT 101, 102, or 104 or an appropriate placement test score.

(2) Cheating: Any student guilty of cheating will be given a '0' on that assignment, final, or test. Additionally, the incident will be formally reported to the Vice President for Student Services. See the Student Handbook for additional information.

(3) Tutoring Center: Tutors are available in the tutoring center if you wish to use them. Go to Bladen 107 or see below for more information.

(4) Test Administration: All tests will be taken in the Testing Center, Bladen 100. Go to to learn about the testing center rules and regulations and operating hours.

(5) Course Pace: It is imperative that you do not fall behind in this course; it is difficult to get caught back up in an online course. Stay abreast of all material and ASK FOR HELP as soon as you need it.

(6) Practice Problems: Suggested problems for you to do are provided for each section of the book (that we will cover) in accordance with the syllabus. Even though the answers/solutions to these problems will not be collected, you must be able to successfully complete these problems, along with the examples in the books, in order to be prepared for the graded assignments/tests and to master the course. Most of the answers to these problems are in the back of the text book, and many of the problems are worked for you in the solutions manual.

(7) Disability Support Services:  Students requesting academic accommodations are required to contact the Disability Support Services Office (M-1042) or call (301) 322-0838 (voice) or (301) 322-0122 (TTY) to establish eligibility for services and accommodations.  Students with documented disabilities should discuss the matter privately with their instructors at the beginning of the semester and provide a copy of their Student/Faculty Accommodation Form.

(8) Code of Conduct:  The Prince George's Community College Code of Conduct defines the rights and responsibilities of students and establishes a system of procedures for dealing with students charged with violations of the code and other rules and regulations of the college.  A student enrolling in the college assumes an obligation to conduct himself/herself in a manner compatible with the college's function as an educational institution.  Refer to the 2004-2005 Student Handbook, beginning on page 39, for a complete explanation of the code of conduct, including the Code of Academic Integrity and the procedure for dealing with disruptive student behavior.

(9) Code of Academic Integrity:  The college is an institution of higher learning that holds academic integrity as its highest principle.  In the pursuit of knowledge, the college community expects that all students, faculty, and staff will share responsibility for adhering to the values of honesty and unquestionable integrity.  To support a community committed to academic achievement and scholarship, the Code of Academic Integrity advances the principle of honest representation in the work that is produced by students seeking to engage fully in the learning process.  The complete text of the Code of Academic Integrity is in the 2004 - 2005 Student Handbook (pages 41 - 43) and posted on the college's website.


Go to Blackboard and click on the Assignments button to see any assignments as they become available.


(1) Grades: Your total score (out of 800 points) on tests, assignments, projects, and the final exam will determine your grade. I reserve the right to use (in a positive manner only) a “fudge factor” based on your participation in the course, especially the assistance you may inadvertently give others by posting good questions or suggestions on the discussion board.
A = 90% of total, B = 80%, C = 70%, D = 60%, F = below 60%

(2) Tests: There will be 4 tests of 100 points each. Your lowest test grade for the semester will be dropped.  If less than three tests are taken, you will receive a grade of zero for those tests short of the three test minimum and your grade will be counted out of 700 points.   All tests will be given at the Testing Center, during a several day period, in accordance with the schedule on the syllabus. Make-up tests will be given only in emergency circumstances and only after the student has already missed one previous test. Make-up tests, if necessary will be given during the last week of the semester (final exam week).  If you take less than 3 tests and are not granted a make-up, you will receive grades of zeros for untaken exams to make three exam grades.

(3) Assignments: There will be 4 graded assignments of 50 points each, of which only the top 3 will be counted toward your final grade. Students must turn-in a minimum of 3 assignments or receive a zero for those assignments short of the 3 minimum. Assignments will be posted several days prior to when they are due; they will be due on the date specified in the syllabus. No late assignments will be accepted and no make-up assignments will be given. Assignments can be passed to me copied into digital drop box in Blackboard.

Assignments must either be completed using Microsoft Word or some other word processing software that I can access or you can complete the assignment by hand, scan the document and send the electronic file.  There will be a trial document for you to send the first week of class to be sure that you send a document correctly.

(4) Projects: There will be two projects that will require you to use Excel. The projects will be posted and discussed later in the course. There combined scores are worth 50 points.  These will also be submitted electronically through the Drop Box in Blackboard.

(5) Final Exam: The final will be 200 points (29% of your course grade). The final must be taken at the Testing Center, during the period specified in the syllabus.
