Plagiarism is cheating: it penalises honest students. Put simply, it is taking somene's work and using the work as your own. Here are some simply guidelines for you to follow: What you can do
You can use another person's writing and ideas only if you acknowledge them as the author within the text and in a bibliography.
If you quote their work directly you must use "quotation" marks.
If you change the words but not the ideas you must still make reference to the author.
What you cannot do
If you copy, cut and paste, any writings, ideas or concepts without citing the author or stating from where you got the information, you are plagiarising. That is, you are stealing another person's intellectual property.
You cannot copy directly from a piece of writing and use it as your own even if you acknowledge the author. For example you cannot download or photocopy an encyclopaedia article and present it as your own work.
You cannot get your parents or brothers and sisters to write your assignment.
