Due to the nature of the course, repeated absences are likely to result in lower grades. In other words, attendance is not mandatory, but tests and homework assignments will relate to material covered in the classroom, which is not always the same as material covered in your textbooks and other readings. Therefore, absences can severely influence your ability to get a good grade in the class. The grade of I, or incomplete, is available for special cases where the student is unable to finish the course by the scheduled end of the term. Granting the grade of I, and setting a date for its completion remain at the total discretion of the instructor.
Plagiarism is academic dishonesty.
In other words, it's a big word for cheating. If you are caught plagiarizing, or cheating in some other form, then you may wind up failing the assignment you were working on, or, if the infringement is serious, the course as a whole. The common form of plagiarism is using someone else's work as if it were your own. That is, by copying the work of another person and presenting that work as if you wrote it, you are plagiarizing. To avoid plagiarism you should learn how to paraphrase and how to use quotation marks.
