How to Avoid Plagiarism in Your Assignments

What Actually Counts (Most People Get One of These Wrong)

Copying text directly. No quotation marks, no citation – this is the obvious one, and detection software catches it easily.

Patchwriting. Rewording a source sentence by sentence, keeping its structure and most of its vocabulary. There’s no single copied sentence here, which is exactly why it still counts – you haven’t actually processed the idea, you’ve just repackaged the wording.

Reusing your own old work. Submitting large chunks of a previous assignment as if it’s new. Students assume this is fine because it’s technically “their own” writing — most UK universities don’t see it that way, and neither does the plagiarism policy you signed up to.

Undisclosed AI-written content. Where your course requires disclosure and you skip it. This one genuinely varies by institution and even by assignment brief, so don’t assume a blanket rule – check the specific one you’ve been given.

Paraphrasing an idea without citing it. This is the one that actually catches most people out. Plagiarism isn’t only about copied wording – if you take someone’s argument or finding and put it in your own words with no citation at all, that’s still plagiarism. The idea needed acknowledging, not just the sentence.

Referencing Is the Mechanism, Not the Paperwork

It’s easy to treat citing sources as a box-ticking exercise tacked onto the end of your writing. It’s actually the thing doing the work. Every time you attribute a claim using Harvard, APA, OSCOLA or MLA, you’re drawing a visible line between what you found through research and what you’re arguing yourself. That line is what a marker is actually checking for, not just whether your citation format is tidy.

A Method for Paraphrasing

“Use your own words” isn’t instruction, it’s just a wish. Try this instead:

1. Read the passage, then close it. Paraphrasing with the source open in front of you is how patchwriting happens.
2. Write the idea from memory, in your own sentence structure, not following the original line by line.
3. Compare afterwards and check you haven’t accidentally mirrored the original’s phrasing or order.
4. Cite it anyway. Paraphrasing removes the need for quotation marks. It doesn’t remove the need for a citation.

If you’re still unsure, getting a second review from a reliable academic support source such as domyassignmentuk.co.uk can help you identify whether your citations and paraphrasing meet university standards before submission.

Turnitin Score

A similarity percentage on its own doesn’t mean much. It flags anything matching another source – including your properly quoted material and your own reference list. A report showing 20% similarity, with all of it landing on cited quotes and your bibliography, looks completely different from 20% concentrated in your actual analysis. What a marker checks is where the matches sit and whether they’re cited, not the number by itself.

If a Similarity Report Has You Worried

• Look at where the flags actually are – matches on quotes and your reference list are expected, not a red flag.
• Check whether flagged paraphrased sections have a citation. If they do, and the wording is genuinely yours, you’re probably fine.
• Ask your tutor before you submit if you’re still unsure. Universities generally prefer an early question over a late panic.
• If you want a second pair of eyes on the specific sections you’re worried about, before you submit rather than after, our editing and reference-check support can look at exactly that.

A Checklist You need to Keep Somewhere Visible

• Every paraphrased idea has a citation, not just every direct quote
• No section has been reworded sentence-by-sentence from a source with the original open in front of you
• Nothing from a previous assignment has been reused without permission
• AI-generated text (if used at all) matches what your specific brief actually allows
• You’ve checked your similarity report by location, not just by the headline percentage

Direct Questions, Direct Answers

Is a high similarity score always a problem? No. Long reference lists, direct quotes, and common academic phrasing all push the number up without indicating actual plagiarism. What matters is whether the matched text is cited.

Can accidental plagiarism still get me in trouble? Yes – most policies don’t require intent, only that the acknowledgement was missing. That’s exactly why building the habit matters more than worrying retroactively.

Does AI-written text count as plagiarism? Depends entirely on your institution’s policy and what your specific brief allows. Some courses permit disclosed use for certain tasks, others don’t allow it at all – check the actual document you’ve been given rather than assuming.

Build the habit properly at the source: Harvard, APA 7th, OSCOLA, MLA, and how to cite a journal article in any of them.
