What it looks like
An example from Biology.
As temperature rises, enzyme’s and substrates collide more often, so the rate of reaction decreases. Above the optimum, there active sites change shape and the substrate no longer fits.

Why markers write it
Markers read many scripts in a row, and errors interrupt them. A few typos rarely change a mark, but they suggest the work was rushed, and a slip that changes your meaning, like “decreases” for “increases”, can cost marks for accuracy. Most UK marking criteria include clarity of expression, so frequent errors usually count against you somewhere.
How to fix it in your next essay
- 1Leave a gap before proofreadingFinish the draft, then wait, ideally a day. You’ll see what you wrote, not what you meant.
- 2Read it aloudReading aloud, or using text-to-speech, slows you down enough to catch missing words and clumsy sentences.
- 3Keep a list of your usual slipsMost people repeat the same few errors. Search your draft for yours: its/it’s, there/their, affect/effect.
How much it costs
A handful of typos rarely moves a mark much in UK schemes, but frequent errors usually count against clarity and presentation, and slips that change your meaning can cost accuracy marks too.
Other ways markers say it
- “Careless errors”
- “Check your spelling and grammar”
- “Needs proofreading”
- “Typos”
- “Sloppy presentation”

Common questions
- Isn’t spellcheck enough?
- No. Spellcheck misses real words in the wrong place, like “there” for “their” or “decreases” for “increases”, and those are often the slips that matter.
- Do markers take marks off for each typo?
- Not usually. But frequent slips tend to lower the mark for presentation and clarity, and can make your argument harder to follow.
- Can someone else proofread my essay?
- Often, for spelling and grammar, but check your university’s proofreading policy first. Many limit what someone else can change.
