6 6 OTHER REQUIREMENTS: A scientific or graphing calculator is required. GRADING POLICY: Instructor s Grading Policy: The grading policy for each section will be provided by the individual instructor at the first class meeting. However, the use of dimensional analysis/conversion factors to solve problems are required. General Guidelines: from the text and OWL not more than 10% Quizzes not more than 20% Class participation not more than 5% Unit Examinations (a minimum of 3) 50 to 75% Final Examination (comprehensive) 15 to 25% 1. Any examination not taken will receive a grade of zero. Make - up examinations will be administered in accordance with the instructor's policy. 2. Any student caught cheating (including using unauthorized formula sheets of any kind) will receive a grade of zero on that particular examination or paper. That zero cannot be replaced by any other examination grade or extra work. Please read The Bergen Community College Statement on academic integrity as found in the college catalog. 3. Late work is not accepted unless specifically authorized by the instructor. 4. Instructors may make minor modifications to the grading guidelines. ATTENDANCE/LATENESS POLICY: All students are expected to attend punctually every scheduled meeting of each course in which they are registered. Attendance and lateness policies and sanctions are to be determined by the instructor for each section of each course. These policies will be established in writing by each instructor and distributed to students at the start of the semester. Attendance will be kept by the instructor for administrative and counseling purposes. OTHER POLICIES: Electronic Devices: The use of portable electronic devices such as pagers and smart phones is not permitted while class is in session. Please silence these devices before entering class. Code of Student Conduct: Students are encouraged to read, understand and follow the rules and standards of conduct as explained in the Student Handbook. The Student Handbook is available in the Office of Student Life and on the BCC website. STUDENT SUPPORT SERVICES: The General Chemistry support class, CHM-142, is recommended for students experiencing difficulty with chemistry-related arithmetic and algebraic problem solving. Late registration for this 1 credit hour class is allowed and encouraged.

7 7 Additionally, The STEM Learning Center in Room S-315 and the Tutoring Center (L-125) provide student support in chemistry, math and other sciences. Faculty office hours may be a productive vehicle for assistance in understanding the course material. The BCC Library provides extensive support services for student research. SERVICES FOR STUDENTS WITH DISABILITIES: Bergen Community College aims to create inclusive learning environments where all students have maximum opportunities for success. Any student who feels he or she may need an accommodation based on the impact of a disability should contact the Office of Specialized Services at or via at ossinfo@bergen.edu for assistance. FACULTY ABSENCE PROCEDURE: A daily listing of cancelled classes will appear in a glass case near the main corridor on the first floor. Another such listing will appear in a glass case in Ender Hall. Students can consult these cases before going to class. Cancelled classes are also listed at bottom of the BCC website page, under class cancellations. Under no circumstances are notices taped to classroom doors regarding class cancellations binding. If students find a class cancelled which has not been listed, they should report this to the Divisional Dean s Office, A-304 or the Evening Office C-107. All BCC students enrolled in credit courses are entitled to a WebAdvisor account. With WebAdvisor, you may register online, pay your bill, check your schedule, room assignments, GPA, and find out what courses you need to take. To find out more about WebAdvisor or to sign up online, visit < While there, please make sure you give us your preferred address. You'll find directions how to do this at < 3/18
