If you are in another program for which you plan to transfer to a 4-year institution, and will need to take calculus, then you should NOT register for Math 135. Instead you should register for Math 163 College Algebra. If you have questions about the Mathematics course required for your program, please consult your program coordinator.

6 ATTENDANCE POLICY Attendance at each class and lab is essential. Please be on time. Students with a legitimate problem about attendance should discuss the situation with their instructor. NOTE: The deadline for withdrawing from a course or changing to an audit for the SPRING 2010 semester is April 12 for full semester OR March 5 OR April 26 depending on shorter session. Failure to officially withdraw from a class you have stopped attending may result in an "F" grade. COURSE REPEAT POLICY Policy on Repeated Courses, page 194 of the CCBC catalog states, Students may repeat a course only once without permission. When a student repeats a course, only the higher grade is computed into the Quality Point Average (QPA). All grades will remain on the student s transcript. Before a student is permitted to register for the course for a third time, the student must have the permission of the academic dean responsible for the course. Before a student may repeat a developmental course that he or she has failed twice, the student s record must be reviewed by a support team which will make recommendations regarding enrollment. Please note: The instructor does not have the authority to grant permission to register for a third attempt at the course. DISABLED STUDENTS In accordance with the Americans with Disabilities Act, CCBC is committed to providing an environment that is conducive to learning for all students. Any student who is disabled and requires special accommodation should contact the appropriate campus as follows: Campus: Office: Room: Phone: Catonsville Office of Disabilities Support Services K Dundalk Office of Career and Life Planning A Essex Office of Disability Support Services A CODE OF ACADEMIC INTEGRITY For the College to make its maximum contribution as an institution of high learning, the entire college community must uphold high standards of integrity, honesty, and ethical behavior. In seeking the truth, in learning to think critically, and in preparing for a life of constructive service, honesty is imperative. Each student has a responsibility to submit work that is uniquely his or her own, or to provide clear and complete acknowledgement of the use of work attributable to others. To these ends, the following actions are expected of students: Complete all work on exams without assistance. Follow the professor s instructions when completing all class assignments. Ask for clarification when instructions are not clear. Report to the instructor any unauthorized information related to an exam. Provide proper credit when quoting or paraphrasing. Submit only one s own work. Students who do not accept responsibility for the integrity of their own work will experience sanctions, including a written reprimand, failure of the assignment, failure of the course, and/or dismissal from the program. For repeat and extreme offenses, the College reserves the right to suspend or expel students. WRITING POLICY The College recognizes that clear, correct, and concise use of language is characteristic of an educated person. Therefore, whenever possible, faculty members in all disciplines should require written assignments in their courses in order to encourage effective writing by their students. Also, instructors should consider the quality of writing in determining a grade for a written assignment. Poor writing can be a sufficient cause for a failing grade on a paper and, in extreme cases, a failing grade in a course. INCLEMENT WEATHER/EMERGENCY CLOSING POLICY In the event that the college (or a specific campus) opens late due to weather-related or other emergency conditions, classes will commence at the announced opening time and resume the normal schedule thereafter for the remainder of the day. Faculty, students, and classified staff should report to wherever they would normally have been at the announced opening time. ** Students and faculty engaged in field placement programs (such as internships, clinical placements, etc.) should discuss the handling of emergency situations at the beginning of the placement period. Both the requirements of the program and the safety of persons involved should be considered in planning a course of action in those cases where students are expected to report to off-campus locations.

7 ** For example, if you had a class that began at 9:35 and the college opened at 10:00 because of snow, you would report to your 9:35 class at 10:00. When the college closes because of severe weather or emergency conditions, announcements of class cancellations are made on local radio and television stations and the college website ( Closings and delays will also be recorded on the campus weather lines: WEATHER CLOSINGS Catonsville, Dundalk, Essex TUTORING SERVICES Students are encouraged to seek help from their instructors whenever they encounter academic difficulty (either during scheduled office hours or by appointment). In addition, each campus offers free academic support services. For more information, contact: Campus: Office: Room: Phone: Catonsville Tutoring Services F Dundalk Tutoring Services CAR Essex Student Success Center A CIVILITY AND COMMUNITY BUILDING EXPECTATIONS Creating a Culture of CARE (Compassion, Appreciation, Respect, Empowerment) As members of the CCBC community of learners, we are expected to act with respect, honesty, responsibility and accountability. Each of us is expected to be aware of the impact our behavior has on the community. CCBC wishes to each learner to commit to the following actions: Become an active and engaged learner Celebrate the richness of our diversity Respect the campus and its code of conduct Practice empathy and compassion Promote the empowerment of others MAJOR RELIGIOUS HOLIDAY POLICY Students not attending class because they are observing major religious holidays shall be given the opportunity, to the maximum extent possible, to make up, within a reasonable amount of time, any academic work or tests they miss. Arrangements between the student and the faculty member(s) for the student to make up missed assignments or tests must be made in advance of the religious holiday, at the initiation of the student. STUDENT ACCOUNTS CCBC has joined the ranks of the very few community colleges in Maryland who provide accounts to all credit students. Each student who is registered in credit classes now has an account and up to 5 Mb of storage in their mail box. This account will not be deleted even if the student graduates or leaves CCBC for any reason. For information about the system and how students can determine their address, go the CCBC Home Page and click on Student . From here students can find their address, get to an on-line user manual and access instructions on how to forward the CCBC to the system of choice (AOL, Comcast, Hot Mail, etc.) TESTING CENTER All tests for this course are taken at the testing center of your home campus. The tests are standard pencil/paper test and you are required to show all work. Regardless of which testing center you use, it is your responsibility to make an appointment at least a week before you plan on taking your test. A complete list of dates for exams is listed in the course calendar. You can either or call the testing center of your home campus to make an appointment. Contact information is listed below and can be found at Required Testing Material: Make sure you bring along a picture ID Pencils and rulers to take your test with. Your calculator. Remember TI 89 and TI 91 calculators are prohibited.
