5 Citation Mistakes That Could Cost You Marks

Citation errors are one of the most common reasons students lose easy marks — not because the research is wrong, but because the formatting doesn't match what the rubric expects. Here are five mistakes to check for before you submit.

1. In-Text Citations That Don't Match the Reference List

Every source cited in your text needs a corresponding entry in your reference list or bibliography, and vice versa. Use your word processor's find function to cross-check author names and years against your reference page.

2. Mixing Citation Styles

APA uses (Author, Year), while MLA uses (Author Page Number). Mixing the two — even accidentally when copying notes from different sources — is an easy way to signal inconsistency to a grader.

3. Missing Page Numbers for Direct Quotes

Both APA and MLA require a page number (or paragraph number for web sources without pagination) any time you quote text directly. Paraphrased ideas need a citation too — just without the quotation marks.

4. Incorrect Alphabetization or Hanging Indents

Reference lists should be alphabetized by the first author's last name, and most styles require a hanging indent (the second and subsequent lines of each entry are indented). This is a small formatting detail that's frequently overlooked.

5. Citing Sources You Didn't Actually Read

If you found a quote inside another article, cite it as a secondary source (e.g., "as cited in") rather than citing the original directly — unless you've read the original yourself. This keeps your research trail honest and traceable.

Running your final draft through a citation checker, or asking your editor to do a dedicated reference pass, can catch most of these issues in minutes.
