Plagiarism is passing off somebody else’s work as your own. If the exam board catches you doing this, you would automatically fail the course, and it could put your other exams in jeopardy as well.
Authors don't mind students quoting them, as long as their name is mentioned in the text whenever you refer to their work. You also need to include the author in your bibliography.
If you don't include references [references: if you have directly quoted someone else, then you must include them in your references ] for original text, you'll be guilty of plagiarism [plagiarism: copy a piece of work and passing it off as your own ].
Whenever you use words straight from a text, you should put quotation marks around them, and give a reference to show where the text came from.
