While a W does not affect your GPA, it may have impact if you are receiving Financial Aid. Before withdrawing from any class, you should consult with your counselor, or a Financial Aid representative. ACADEMIC INTEGRITY Academic integrity is submitting one's own work, and properly acknowledging the work of others. Any violation of this principle constitutes academic dishonesty. Forms of academic dishonesty include: Plagiarism Submitting another's work, in whole or part, as one's own. This includes an examination, a computer program, a laboratory report, or a written assignment. Facilitating Academic Dishonesty Helping another commit an act of dishonesty, such as substituting for an examination or completing an assignment for someone else. Cheating Using or attempting to use unauthorized materials on an examination or assignment, such as using unauthorized texts or notes or improperly obtaining, or attempting to obtain, copies of an examination or answers to an examination. Illegal System Access Altering, transmitting, or permitting unauthorized individuals access to your account, or an attempt to alter or destroy system files on any server or computer. This also includes altering, transmitting, or attempting to alter or transmit academic information or records by unauthorized individuals. Students that participate in dishonest activities ♦ will receive a 0 for that project, examination, or assignment ♦ may be given a grade of F for the course ♦ may be reported to the Dean for disciplinary action For additional information, refer to the current Brookdale Community College Student Handbook.
