How to Avoid Submitting AI Slop (and Getting Average Marks)

If you’re trying to improve your grades or feel like you’re struggling with uni writing, relying on AI to generate your ideas is one of the fastest ways to cap your marks.

Not because AI is “bad,” but because of how it works: it’s an input–output prediction system. It predicts the most likely next word based on patterns in its training data. That means the writing it produces is conventional, predictable, and deeply unoriginal — the exact opposite of what markers reward.

AI predicts likely word combinations — not good ideas

Most students worry about AI hallucinations (like fake sources), and yes, those can get you into serious trouble. But the deeper issue is this: AI doesn’t generate insight. It generates probability‑safe sentences. So even when it’s factually correct, it’s still surface‑level, and idea‑poor.

Markers read hundreds of assignments in a row. They can spot AI‑style writing instantly because it all sounds the same: empty, and painfully conventional.

“Garbage in, garbage out” (the real rule)

AI is only as good as the ideas you feed it. If you give it vague prompts, you get vague writing. If you give it no ideas, you get AI slop — the kind of writing that earns “pass” or “credit” at absolute best.

The shortcut test: If the idea didn’t come from you, it won’t impress your marker.

Why AI writing feels boring to academics

Your marker has gone through a PhD. That means they’ve spent years learning to think in ways that are not conventional. Academic work rewards:

  • originality

  • critical analysis

  • insight

  • interpretation

  • intellectual risk

AI can’t do those things. It can only remix what already exists. So when you hand in AI‑generated ideas, you’re handing in the most statistically average version of the assignment (and you’ll get the most statistically average result, a low credit).

When AI can help (and when it absolutely shouldn’t)

Use AI after you already have strong ideas — not before. Good uses:

  • polishing sentences

  • tightening structure

Bad uses:

  • generating your argument

  • generating your interpretation

  • generating your analysis

  • generating your “original contribution”

·Here’s the shortcut: if the thinking isn’t yours, the writing won’t be good.

Want help developing ideas so you don’t rely on AI?

·If you want to improve your marks, build stronger arguments, or stop feeling like you’re struggling with uni writing, you can book a tutor and learn how to generate original, high‑quality ideas (that AI can then help you polish).
