Why Citation Accuracy Directly Dictates Your Grade
In academic grading rubrics across US, UK, Canadian, and Australian universities, referencing and bibliography mechanics frequently account for **10% to 15% of your total assignment marks**. Moreover, inconsistent or missing citations can trigger plagiarism investigations.
Different disciplines require different citation styles because each academic community prioritizes different details:

Quick Verification Tip
Always double-check DOIs (Digital Object Identifiers). If an online source has an assigned DOI, prefer the DOI link over a standard web URL.
