10 common CELPIP Writing mistakes (and how to fix them)
The recurring CELPIP Writing mistakes that quietly cap your level — from missing a bullet point to fence-sitting — with a quick fix for each.


⚡ The short version
- Most lost marks come from a few repeat mistakes, not from weak English.
- Cover every bullet, commit to one side, and match the tone to the reader.
- Leave two minutes to fix the easy wins: spelling, sentence variety, a clear close.
When CELPIP Writing scores come in below where someone expected, it's rarely a vocabulary problem. It's almost always one of the same handful of habits, repeated across both tasks. Here are the ten we see most — and the quick fix for each.
1. Missing a bullet point
Task 1 lists three or four things to cover; they're a checklist, not suggestions. Miss one and your Task Fulfilment score is capped before anything else is read. Fix: tick off every bullet before you submit.
2. Burying your purpose
If the reader has to hunt for why you're writing, you've spent goodwill you can't get back. Fix: state your purpose in the first sentence.
3. Fence-sitting on Task 2
Task 2 asks you to choose one of two options. "Both have advantages" reads as no position. Fix: pick the side you can argue best and commit from sentence one.
4. Long words over precise words
Vocabulary is scored on precision, not length. A misused fancy word hurts more than a plain accurate one. Fix: choose the exact word, not the impressive one.
5. One giant paragraph
A wall of text is hard to mark and reads as disorganised. Fix: use clear paragraphs — greeting/purpose, the details, a close.
6. The wrong tone
A building manager isn't your best friend; a friend isn't a formal official. Mismatched register costs Task Fulfilment. Fix: picture the reader and match your formality to them.
7. The same sentence opener every time
"I think… I want… I need…" line after line reads flat. Fix: vary how sentences start; it lifts Readability with no extra effort.
8. Ignoring the word count
Both tasks want roughly 150–200 words. Far under looks underdeveloped; far over wastes time and rambles. Fix: watch the on-screen counter and aim for the band.
9. No clear closing line
Trailing off mid-thought leaves a weak final impression. Fix: end with one sentence that matches the email's purpose — a thank-you, a next step, a request.
10. Not leaving time to proofread
Easy spelling and grammar slips are the cheapest points to lose. Fix: reserve the last two or three minutes to read your response once, slowly.
None of these are about knowing more English — they're choices. Fix the recurring ones and most stalled Writing scores move up a level. See exactly how the tasks are marked in how Task 1 is scored, then practise with AI feedback.
