Plagiarism is presenting others' words, ideas, or creative works as one's own. A study found that 74% of students admitted to serious test cheating and 72% to cheating on written assignments, with over half admitting some level of plagiarism using the internet. Plagiarism can be intentional, such as copying others' work, or unintentional through careless paraphrasing or poor citation. Consequences for plagiarism range from failing grades to suspension or expulsion.
