Plagiarism is portraying the work or ideas of someone else as your own, with or without their permission, by integrating it without full acknowledgment into your work.
From the outset of your university career, the only way to prevent plagiarism is to understand and employ the concepts of good academic practice. Avoiding plagiarism is not just a matter of ensuring that all your sources are right, or modifying enough terms so that your paraphrase is not found by the examiner; it's about using your academic knowledge to make your job as good as it can be.
Before beginning the review process, the submitted manuscript is reviewed for plagiarism.
Usually, up to 15% plagiarism is acceptable if it’s more than that the manuscript is sent back to the author and advised to revise and resubmit the manuscript.
