PTE diagnosis
20 most common PTE mistakes (and how to fix them)
If your mock scores are stuck 5 to 15 points below your target, you are almost certainly making 3 or 4 of the mistakes on this list. Each one has a clear cause, a specific cost in points, and a fix you can apply in your next practice session. Diagnose yours, then take a scored mock test to see whether the fix landed.

The pattern
Why candidates underperform on mock tests
PTE Academic is an algorithmically scored exam with 22 task types across 3 sections in about 2 hours. It is designed so that a small number of technical errors, repeated across items, produce a much larger drop in your overall score than the errors would suggest. The scoring model is trait-based: each speaking item is scored on Content, Pronunciation and Oral Fluency (with human review of Content on 7 task types); each writing item on Content, Form, Grammar and other traits; each reading and listening item on partial credit, with negative marking on exactly three task types.
That structure produces a specific failure pattern. Candidates typically lose 5 to 15 points not from lack of English, but from breaking a form rule (essay word count, SWT single-sentence rule), triggering template detection, ticking too many options on MCMA, or under-preparing for the no-break 2-hour test. On our platform, about 8 in 10 attempts under 65 show at least one of these mistakes on repeat, and roughly 4 in 10 attempts under 79 show 2 or more.
This guide is the checklist of the 20 mistakes we see most often, organised by section, with the exact cost in points and the fix. Read it end-to-end before your next practice mock, then use the PTE 79 strategy or PTE 65 strategy to pick your target band and drill the mistakes that block it.

| Listening | Listening (5 mistakes) | 5 |
| Test-day | Test-day (1 mistake) | 1 |
Section boundaries follow the official PTE Academic Test Taker Score Guide (July 2025). Test-day mistake is separate because it affects every section at once.
Prioritise by target
Fixes ranked by score target
Not every mistake matters equally at every band. If you are chasing 65, start with the ones that cost easy points. If you are chasing 90, zero-out the lot.
PTE 65 (Proficient / 10 PR points)
Fix mistakes 1, 6, 7, 10, 12, 14, 15, 20 first. These are the score-killers that stop candidates crossing 65.
Read the strategy guide →PTE 79 (Superior / 20 PR points)
Fix mistakes 5, 8, 11, 13, 16, 18 as well. At this band, small precision errors decide whether you clear Writing 85 and Speaking 88.
Read the strategy guide →PTE 90 (top band)
Zero-out every mistake on the list. At this band, one item lost per section is the difference between 88 and 90.
Read the strategy guide →Section 1 of 4
Speaking mistakes (1 to 5)
The trait model punishes any speaking item where Content scores 0. Watch these five closely.
- 1
Reciting memorised templates on Describe Image
Cost: Content trait can drop to 0, capping the item
Problem. Word-for-word scripts trigger Pearson's template detection. If Content is scored 0 (because the words do not describe the specific image), the whole item scores 0, no matter how fluent you sound.
Fix. Use a light framework (title, biggest trend, 2 specifics, closing), not a script. Every sentence must mention something visible in the actual chart or diagram in front of you.
- 2
Waiting for a tone on Repeat Sentence
Cost: First seconds of your 15s answer window wasted
Problem. Repeat Sentence has no beep. The recording starts the moment the microphone icon appears. Candidates trained on other tasks freeze, then rush the sentence with poor fluency.
Fix. Start speaking within about half a second of the icon appearing. Read our Repeat Sentence practice hub and drill until the reflex is automatic.
- 3
Pausing for more than 3 seconds
Cost: Recording auto-stops, item may cut off mid-answer
Problem. The system detects silence longer than roughly 3 seconds and treats it as end-of-answer, cutting your recording. This is common on Retell Lecture when candidates lose their train of thought.
Fix. Keep a filler noise (a short pause, not "um") but do not go silent. If you lose your place, restart the sentence rather than stopping.
- 4
Whispering into the microphone
Cost: Pronunciation and Oral Fluency scored low
Problem. Test centre nerves push candidates to whisper. The AI scores what it can hear, and quiet audio degrades pronunciation and fluency estimates even when the words are correct.
Fix. During the equipment check, speak at natural conversation volume and confirm the level meter moves. Keep the microphone about 3 to 5 centimetres from your mouth.
- 5
Fake accent chasing
Cost: Pronunciation drops as intelligibility drops
Problem. Copying an American or British accent you cannot sustain adds hesitation, distorted vowels and inconsistent stress. Pronunciation is scored on intelligibility, not on which accent you use.
Fix. Speak in your natural clear accent, at your natural pace. Focus on word stress and sentence rhythm, not accent imitation. Our speaking practice hub covers this in detail.
Drill these on our speaking practice hub, or target the highest-value tasks directly: Repeat Sentence, Describe Image, Retell Lecture.
Section 2 of 4
Writing mistakes (6 to 10)
Writing has the strictest form gates on the exam. Break the word limit or the sentence rule and your item scores 0.
- 6
Breaking the essay word limits
Cost: Content trait zeroed if outside 120 to 380 words
Problem. The essay Form trait is a zero-gate: fewer than 120 words or more than 380 words scores 0 on Content regardless of how good the argument is. Many candidates go over when they rush the conclusion.
Fix. Aim for 220 to 280 words. Use the live word count that appears on the writing screen. Leave 2 minutes at the end to trim, not to add.
- 7
Writing Summarize Written Text as two sentences
Cost: Item scores 0 on Form
Problem. SWT must be exactly one sentence between 5 and 75 words. Two sentences, a semicolon that reads as two clauses, or an accidental full stop mid-answer all zero the Form trait, which zeroes Content.
Fix. Draft your summary, then verify: one initial capital, one final full stop, no full stops in between. Use commas, colons or dashes to join clauses.
- 8
Copy-pasting whole sentences from the source
Cost: Vocabulary and Grammar traits score low
Problem. SWT and essay traits reward paraphrasing and range. Verbatim strings from the source text lower Vocabulary and General Linguistic Range, even when the sentence is grammatically correct.
Fix. Read, close your eyes for a second, then write in your own words. Change nouns to synonyms where you can and vary the sentence structure.
- 9
Ignoring the essay prompt to reuse a memorised argument
Cost: Content trait drops sharply
Problem. Candidates who prepare one "about technology" essay try to force it onto every prompt. If the prompt is about universities and your answer is about smartphones, Content is scored against the prompt, not against your fluency.
Fix. Spend the first minute planning: paraphrase the prompt in your notes, decide your position, list 2 supporting points that answer THIS prompt.
- 10
Skipping spellcheck on Write from Dictation
Cost: Every misspelled word scored 0 for that word
Problem. WFD is scored word by word. A misspelled word counts as wrong, even if you clearly heard the right one. Common: "recieve", "seperate", "acheive", "occured".
Fix. Learn the 20 words you personally misspell. Build a written list. Practise on our Write from Dictation drills and grade honestly.
The Form zero-gate
Essay under 120 or over 380 words: Form scored 0. Summarize Written Text as more than one sentence or outside 5 to 75 words: Form scored 0. Either zeroes Content. Learn the rules on our writing section guide.
Section 3 of 4
Reading mistakes (11 to 14)
Reading is time-constrained. Waste 4 minutes on Reorder Paragraphs and you sacrifice 3 easier items.
- 11
Guessing on Reading MCMA under negative marking
Cost: Minus 1 per wrong tick, minimum item score 0
Problem. Multiple Choice Multiple Answers in Reading has negative marking. Ticking every plausible option to hedge does not help: each incorrect tick removes a point earned by a correct one.
Fix. Tick only options you can defend from the passage. If unsure between 2 and 3 correct answers, submit 2. Never submit 5.
- 12
Reading Reorder Paragraphs top to bottom
Cost: Wastes half the section budget on one item
Problem. Reading is 22 to 30 minutes for 13 to 20 items. Candidates who read every paragraph fully and then try to reorder run out of time. Reading FIB, MCMA and MCSA get sacrificed.
Fix. Read the first sentence of each paragraph, spot the topic sentence and pronoun anchors (this, these, they, however), then place the paragraphs. Fine-tune only if time allows.
- 13
Guessing dropdowns without reading the surrounding sentence
Cost: Each wrong dropdown loses an item point
Problem. Reading and Writing Fill in the Blanks (Dropdown) is scored partial credit. Candidates who read only the phrase around the gap miss collocations that only make sense with the whole sentence.
Fix. Read the whole sentence first, sometimes the whole paragraph. Collocation and register (formal vs informal, verb tense) usually decide the correct option.
- 14
Skipping questions to come back later
Cost: You cannot
Problem. PTE Academic is Next-only. Once you click Next you cannot return to previous questions in any section. Candidates trained on IELTS lose items they meant to "revisit".
Fix. Answer every question before you click Next. If you truly do not know, guess (except on MCMA where negative marking applies) and commit.
Section 4 of 4
Listening mistakes (15 to 19)
The audio plays once, and 3 tasks have negative marking. Nowhere to hide.
- 15
Trying to take verbatim notes on Retell Lecture
Cost: You miss the next 20 seconds of the lecture
Problem. Full-sentence note-taking guarantees you fall behind. Retell Lecture audio is up to 90 seconds and plays once. You cannot rewind.
Fix. Note only keywords: dates, numbers, names, cause-effect arrows, 3 to 5 nouns per idea. Use symbols (up-arrow, down-arrow, equals). Practise on our Retell Lecture drills.
- 16
Ticking every option on Listening MCMA
Cost: Same negative marking as Reading MCMA
Problem. Listening Multiple Choice Multiple Answers is one of the three tasks with negative marking. The audio plays once, so candidates who did not follow the argument often over-tick to hedge.
Fix. Tick only what you heard. If you missed the audio, submit 0 or 1 options, not 4. A blank item scores 0, not negative.
- 17
Missing the beep on Select Missing Word
Cost: You choose the wrong option because you did not process the context
Problem. The final word of the audio is replaced by a beep. Candidates who half-listen miss the semantic clues in the sentences before the beep and pick the wrong replacement.
Fix. Listen actively from the first second, not from the beep. The correct word is always signalled by context earlier in the audio.
- 18
Typing full sentences on Listening Fill in the Blanks
Cost: Extra words are wrong; you overshoot the timer
Problem. You type the missing word only, not the whole sentence. Some candidates panic and start typing what they hear from the beginning, then delete under time pressure.
Fix. Type only into the empty boxes. Move to the next blank as soon as you complete one. On-screen keyboard shortcuts (Tab) help.
- 19
Ignoring Highlight Incorrect Words after the audio starts
Cost: Missed mismatches, plus negative marking
Problem. HIW displays the transcript, plays the audio, and asks you to click words that differ. Candidates who look up or re-read the transcript before the audio starts get behind. Wrong clicks are minus 1 each.
Fix. Read the transcript once BEFORE the audio starts. When the audio begins, follow along with your cursor and click only clearly mismatched words.
Drill Write from Dictation directly on our WFD practice hub : it is the single highest-value listening task.
The 20th mistake
Test-day: the one that affects every section
- 20
Under-preparing for the 2 hour non-stop format
Cost: Fatigue collapses your last section (usually Listening)
Problem. PTE Academic has NO scheduled break in the current format. Candidates who only practise 30-minute drills are exhausted by the Listening section and lose easy Write from Dictation points.
Fix. Sit at least 3 full timed mocks before test day. Our free mock test is the same length and format as the real exam.

FAQ
Common PTE mistakes, answered
Reciting memorised templates on Describe Image or the essay. The 2025 hybrid AI plus human scoring model checks the Content trait against what you actually saw or were asked. If Content scores 0, the whole item scores 0. Use a light framework instead: read our Describe Image practice hub for the framework we teach.
Speaking and Writing, jointly. Together they contribute the highest weight to the overall score, and they include the highest-consequence trait gates (Form zero-gates on essay word count and SWT sentence structure). Diagnose your specific weak section with a free AI-scored mock test.
Yes, on exactly three tasks: Reading Multiple Choice Multiple Answers, Listening Multiple Choice Multiple Answers, and Highlight Incorrect Words. Each wrong tick or click loses 1 point, and the item cannot go below 0. Every other PTE task type is scored partial credit or straight correct or incorrect, so guessing has no penalty there.
No. PTE Academic is Next-only. Once you click Next, the item is locked. This is different from IELTS or TOEFL. See our exam day tips for the full test-day flow.
Because Content zeroed. If the AI scoring plus human reviewer decide your description does not match the specific image (usually because you recited a script that mentioned things not on the chart), Content becomes 0 and the whole item collapses. Fluency and Pronunciation cannot rescue a 0 on Content.
Approximately 2 hours in the current format, sat in a single sitting with no scheduled break. Candidates who train on 30-minute drills often collapse in the last section. Sit at least 3 full-length mocks before test day. See how many mock tests you need.
The essay must be between 120 and 380 words. Fewer than 120 or more than 380 zeroes the Form trait, which zeroes Content. Aim for 220 to 280 words and use the live word count on screen. See our writing section guide.
