- Plan ahead: Start assignments early to avoid last-minute copying pressure
- Take good notes: Clearly mark which notes are your own thoughts vs. sourced information

Common Types of Plagiarism to Watch For
Submitting someone else’s work as your own without any changes. This is the most serious form and is easily detected by plagiarism checkers.
Copying text word-for-word from a source without quotation marks or citation, even if you copied just a sentence or paragraph.
Reusing your own previously published work in a new context without disclosure. This violates academic integrity and publishing standards.
Mixing copied phrases with your own words, or replacing keywords while maintaining the original structure without proper citation.
Unintentionally failing to cite sources, misquoting, or improperly paraphrasing due to negligence or lack of understanding.
Rewriting someone’s ideas in your own words without giving credit. Even if words are changed, the original source must be cited.
Citing sources incorrectly or incompletely, making it difficult or impossible for readers to find the original source.
