Citing and referencing are some of the most important and common practices in every assignment. Either you are working on a marketing, nursing, or engineering assignment, citing and referencing is an important part of the assignment. Your assignment can fall into the category of plagiarism if you fail to cite your sources and do not give references. This will not only give you poor grades but also lower your credibility among the professors in your university. In engineering assignments, citations and references are whatsoever more important. You can be writing an analytical essay, dealing with a technical project, or designing a report; proper citations allow your work to be high-quality and authoritative.
