The student is expected to attend all classes. It is the student’s responsibility to get work missed from an absence. All work is to be made up within 3 days. Make up work is graded as zero after 3 unexcused absences. In addition, you need to be aware that BRCC expects you to attend every class. School related absences (i.e. sports, choir, etc.) are not recognized by BRCC. Keep absences to a minimum. Notify the instructor and get any work needed before the absence. In a college course, make-up work and tests are given and/or accepted at the sole discretion of the instructor. In case of snow days, work will continue. An online assignment will be given. GRADING POLICY: 80% of the grade is from 7 tests each worth 100 points, various quizzes each worth 50 points, and several projects worth varying amounts of points. 10% of the grade is from homework 10% of the grade is from class participation where 100 points are assigned and the points are deducted for rule infractions and absences. The grading scale will be based on percentages as follows: 90% - 100% A 80% - 89% B 70 % – 79% C 60% - 69% D Below 60% F There will be an exam that will count as 2 test grades. TEXT: Precalculus, 9th Edition, Sullivan; Pearson/Prentice-Hall, 2012 My Math Lab, an internet site with problems that coordinate with the text book. INSTRUCTIONAL MATERIALS: Graphing Calculator will be used extensively in the class. These are available in the classroom for in room use, but the student would benefit from having their own calculator. The student also needs a 3-ring binder or spiral notebook, whichever he/she is best at organizing. The student will also need internet access to do the homework that is assigned to be done on the Course Compass site. CLASS SCHEDULE AND SEQUENCE OF INSTRUCTION: The following is a tentative schedule and is subject to change at any time. We will cover the sections in the order listed, but not necessarily on the dates listed. Students are responsible for all material form the textbook sections listed below whether covered in class or not.

Blue Ridge Community College values truthfulness, respect for the property of others, and honesty in academic work. Violations of these values may result in permanent dismissal from the College. The Statement on Student Rights and Responsibilities, located in the Catalog and Student Handbook, and the Statement on Academic Honesty below, provide specific guidelines which encompass this code. Academic Honesty When College officials award credit, degrees, diplomas, and certificates, they must assume the absolute integrity of the work done by students; therefore, it is important that each student maintains the highest standard of honor in his or her scholastic work. Academic dishonesty cannot be condoned. When such misconduct is established as having occurred, students are subject to possible disciplinary actions ranging from admonition to dismissal, along with any grade penalty the instructor may impose in accord with their syllabus and college policies. Procedural safeguards of limited due process and appeal are available to students in disciplinary matters. Grade disputes about a grade assigned as a result of academic dishonesty can only be resolved through the grade appeal procedure. No withdrawal policy outlined in the College Catalog and Student Handbook can supersede a grade penalty assigned as a consequence of an academic honesty violation. Academic dishonesty includes, but is not limited to, one of the following acts: 1. Cheating on an examination or quiz, including the giving, receiving or soliciting of information, the unauthorized use of notes or other materials during the examination or quiz. 2. Buying, selling, stealing or soliciting any material purported to be the unreleased contents of a forthcoming examination, or the use of such material. 3. Substituting for another person during an examination and/or quiz, including online exams or quizzes, or allowing such substi tution for one’s self. 4. Plagiarism. This is the act of using content and/or ideas from the work of another individual, either word for word or in substance, and representing them as one’s own work. This includes any submission of written work other than one’s own. There are three types of plagiarism as listed in Donald A. Sears’ book Harbrace Guide to the Library and Research Paper, 3rd Edition (New York: Harcourt, 1972, p. 45). They are: a. Word-for-word plagiarism: The submission of the work of another source without proper acknowledgment of that source by footnote, bibliography or reference in the paper. b. Patchwork plagiarism: Submitting a work that is stitched together from a variety of sources that does not indicate direct quotes or acknowledgment of those sources. c. Unacknowledged paraphrase: Restatement or rewording of another author’s original thought or idea must be acknowledged. Restatement by means of paraphrase does not remove the necessity of giving credit to original sources. Refer to the Library website for more information on plagiarism. (http://www.brcc.edu/library/) 5. Collaboration with another person in the preparation or editing of assignments submitted for credit without advance approval from the instructor. 6. Knowingly furnishing false information to the College including, but not limited to, forgery, alteration or use of College documents, or instruments of identification with intent to defraud.
