How the examiner scores you
Before you fix a mistake, it helps to know what is being marked. The examiner gives you a band from 0 to 9, and looks at four things that all count the same amount:
- Fluency and coherence — can you keep talking and make sense?
- Lexical resource — do you have the right words?
- Grammatical range and accuracy — do you use different sentence types correctly?
- Pronunciation — are you easy to understand?
Because the four are equally weighted, you cannot win by being perfect in one and weak in the rest. Most mistakes below hurt one or two of these areas. If you are new to the test, start with the full IELTS Speaking guide.
The ten mistakes (and the fix for each)
Read the table, then try one fix at a time. Do not try to change everything at once.
| Mistake | Why it lowers your band | What to do instead |
|---|---|---|
| Memorised, rehearsed answers | Examiners are trained to spot them. The rhythm sounds flat, and they may stop you or ask a new question you cannot answer. | Learn ideas and useful words, not whole speeches. Speak from a few notes so each answer sounds fresh. |
| Answers that are too short | One-line answers give too little to score. This hurts most in Part 3, where the examiner wants your opinion. | Answer, then add a reason and an example. A good habit: one sentence, then "because…", then "for example…". |
| Too many "um" and "uh" | Constant fillers break your flow and lower fluency. They make you sound unsure. | Slow down and pause in silence to think. A short quiet pause sounds calmer than "ummm". |
| Big words you don't control | A hard word used wrongly is worse than a simple word used well. It hurts your vocabulary and accuracy scores. | Use words you truly know. Aim for the right word, not the fanciest one. |
| Only simple short sentences | If every sentence is short and basic, you cannot show grammatical range, so that score stays low. | Mix in longer sentences with "which", "because", "although", and "when". Show you can build a complex sentence. |
| Speaking very fast to seem fluent | Speed is not fluency. Rushing makes your pronunciation unclear and adds mistakes. | Speak at a calm, steady pace. Being clear counts far more than being quick. |
| Not answering the actual question | If you drift off topic, coherence drops and you may look like you didn't understand. | Listen for the question word (why, how, when). Answer that first, then add detail. |
| Overusing one linking word ("and… and…") | Repeating "and" makes ideas run together and shows a narrow range of linking. | Vary your links: "but", "so", "also", "however", "the reason is". Different links show range. |
| Going silent when you don't know a word | A long silence hurts fluency and coherence, and the examiner cannot score what you don't say. | Paraphrase. Describe the thing another way: "I forget the exact word, but it's the machine you use to…". |
| Trying to fake a native accent | Copying an accent often makes you less clear, and clarity is what pronunciation actually measures. | Keep your own accent. Focus on clear sounds, word stress, and easy-to-follow rhythm. |
The three habits that fix the most
If the table feels like a lot, focus on three habits. They quietly fix many of the mistakes above at once.
1. Extend every answer. After your first sentence, add a reason and an example. This one habit cures short answers, weak Part 3 replies, and "and… and…" lists, because reasons and examples give you real ideas to link. Part 2 is the best place to practise talking longer — see our Part 2 cue card method.
2. Slow down and pause on purpose. A calm pace gives you time to choose the right word and build a longer sentence. It also cuts the "ums", because you are thinking in quiet, not out loud. You will sound more, not less, fluent.
3. Never stop — paraphrase instead. When a word won't come, talk around it. Say what the thing does, looks like, or is used for. Keeping the flow going protects your fluency score far better than freezing.
How to catch your own mistakes
Most of these mistakes are hard to notice while you are talking. The fix is to record yourself and listen back, or get feedback that points to the exact moment things slipped.
- Record a full answer, then listen only for one thing — count your "ums", or mark where you stopped early.
- Time yourself. If you run dry in 15 seconds, you know to work on extending answers.
- Check for range. Did you use any long sentences? Any linking word other than "and"?
- Note the words you avoided. Those are the ones to learn to paraphrase next time.
Doing this by ear is useful, but it is easy to miss your own patterns. Aflo listens to a real answer and shows exactly where fluency drops, which words were unclear, and how each of the four criteria scored — see how the scoring works.
Frequently asked questions
What is the most common IELTS Speaking mistake?
Giving answers that are too short, especially in Part 3. The examiner needs enough language to score, so always add a reason and an example after your first sentence.
Do memorised answers lower your IELTS Speaking band?
Yes. Examiners are trained to recognise rehearsed speech, and it often sounds flat and off-topic. Learn ideas and useful words instead, so you can speak naturally about any question.
Is it bad to have an accent in IELTS Speaking?
No. Pronunciation is scored on how clear and easy to follow you are, not on sounding like a native speaker. Keep your own accent and focus on clear sounds, word stress, and rhythm.
What should I do if I forget a word during the test?
Do not go silent. Paraphrase — describe the thing another way, for example "I forget the word, but it's the machine you use to make coffee." Keeping the flow going protects your fluency score.
