Plagiarism is the act of taking, using, or copying the thoughts, ideas, writings, inventions, etc., of another person and claiming it as your own. It is informally called “copying” mostly from another student or from the Internet. (Canadian Oxford Dictionary of Current English)
Handing in assignments that have been copied from the internet or another student is not tolerated. Teachers will respond in an instructive way, and perhaps in a disciplinary way.
