The one-sentence rule: what you need to follow
For PTE Academic Summarize Written Text, write one complete sentence of 5 to 75 words within 10 minutes. Pearson assesses reading and writing in this task and recommends practising compound and complex sentences. See Pearson's Academic task instructions.
One full stop at the end is a useful check, but it cannot tell you whether your sentence is grammatical. Two complete thoughts joined only by a comma can still be wrong.
Taking PTE Core? Core asks for 25 to 50 words and allows one or more complete sentences. This lesson focuses on Academic. Check Pearson's Core summary instructions before applying the Academic limits.
Choose connectors by meaning, not by difficulty
A clause is a group of words built around a verb, usually with a subject. A complete clause can stand alone: The library extended its hours. The table shows ways to connect ideas without changing what they mean. These are original sentence-building examples, not full exam answers.
| Relationship | Connector and example |
|---|---|
| Add a related point | and: The library extended its hours, and students gained more study time. |
| Show contrast | but: The library extended its hours, but staffing costs increased. |
| Acknowledge a limitation | although: Although staffing costs increased, the library retained its longer hours. |
| Give a reason | because: The library stayed open later because students needed evening study space. |
| Give a result | so: Students needed evening study space, so the library stayed open later. |
| Add information about a noun | which: The library added evening sessions, which gave students more study time. |
Do not swap and for so just to vary vocabulary. If the passage says two things happened but gives no causal connection, so may invent one. Likewise, although needs a genuine contrast.
Worked example: turn a passage into one sentence
This short fictional passage isolates the skill of combining ideas. It is original teaching material, not a recalled Pearson question.
A college introduced recorded lectures to help students whose work shifts prevented them from attending every class. The recordings allowed these students to revisit difficult explanations at a convenient time. However, recordings alone offered no opportunity to ask questions. The college therefore kept its weekly discussion sessions so that students could clarify ideas with a tutor.
1. Keep the message and the important relationship
The message is that recordings improve access but need support from discussion. Keep the benefit, the limitation and the college's response. There is no need to repeat every detail about shifts or schedules.
2. Build a complete main clause
Start with The college retained weekly discussions. It has a subject, the college, and a verb, retained. Now attach the reason and the contrasting benefit.
3. Join, then check
One possible summary: Although recorded lectures helped working students review difficult material at convenient times, the college retained weekly discussions because recordings alone did not allow students to ask questions and clarify ideas with a tutor.
Why it holds together: Although introduces the benefit that contrasts with the limitation; because explains why discussions remain necessary. The main clause still stands on its own. The summary has 33 words and one final full stop.
This is one possible answer, not a scored model or a template to memorize. A different passage may need addition, comparison or a sequence instead of this contrast-and-reason structure.
Five sentence problems and how to repair them
1. A comma between two complete clauses
Problem: The college recorded lectures, working students could review them later.
Repair: The college recorded lectures, so working students could review them later.
Both parts could stand alone. A comma by itself does not join them correctly; this error is called a comma splice. Here, so also expresses the intended result. Purdue OWL explains comma-splice repairs.
2. Treating however like but
Problem: Recordings were convenient, however, students could not ask questions.
Repair: Recordings were convenient, but students could not ask questions.
Another grammatical option: Recordings were convenient; however, students could not ask questions.
When however connects two complete clauses in this pattern, use a semicolon before it and a comma after it. The same pattern can work with therefore or moreover, if the meaning fits. A semicolon joins clauses within one sentence; it does not automatically create a second sentence. This is a grammar explanation, not a promise about an individual PTE score. See Purdue's sentence punctuation patterns.
3. Using although and but for the same contrast
Problem: Although recordings were useful, but discussions were still necessary.
Repair: Although recordings were useful, discussions were still necessary.
Remove but. Alternatively, remove although: Recordings were useful, but discussions were still necessary. The same editing principle applies to because ... so: choose one structure for the cause and result.
4. Leaving only a dependent clause
Problem: Because recordings could not answer students' questions.
Repair: Because recordings could not answer students' questions, the college retained discussions.
The first version leaves the reader waiting for what happened because of that limitation. Add a complete main clause. Put a comma after the introductory because clause; when the reason follows the main clause, you usually do not need that comma. See Purdue's guidance on introductory clauses.
5. Getting the grammar right but changing the meaning
Problem: The college retained discussions, so recordings were convenient.
Repair: Although recordings were convenient, the college retained discussions so students could ask questions.
The problem sentence invents a cause: keeping discussions did not make recordings convenient. A grammatical sentence still needs to represent the passage accurately.
Try it: repair a summary before revealing the answer
Mini-passage: A museum digitized its archive so researchers could consult records remotely. Some handwritten documents were difficult to search because automatic text recognition was unreliable. Staff therefore checked those documents and added searchable descriptions.
Draft to repair: Although the digital archive allowed remote access, but handwritten records were difficult to search, therefore staff added descriptions.
Keep the three essential ideas: access, the search problem and the staff response. Remove the doubled contrast and fix the join before the result.
Reveal one possible repair
Although the museum's digital archive allowed remote access, handwritten records remained difficult to search because automatic text recognition was unreliable, so staff checked those documents and added searchable descriptions.
This 29-word sentence keeps the reason for the search problem. Although introduces the contrast, because gives the reason and so connects the staff response. Other accurate, grammatical versions are possible.
Check your summary before submitting it
- Meaning: does it capture the central message without adding your opinion or an unsupported cause?
- Complete sentence: can you identify a main subject and verb, rather than only an although or because clause?
- Joins: look at every comma. If it sits between two complete clauses, check the connector and punctuation.
- Form: check the Academic word range and one-sentence instruction. Keep normal capitalization for proper names and the word I; one sentence does not mean only one capital letter anywhere.
- Final edit: check agreement and spelling, then remove repeated ideas.
Use the PTE word counter for a length check. A word counter cannot decide whether your ideas are accurate or your clauses are joined correctly.

MocksPTE provides basic checks for word count, sentence endings and key ideas. These checks can miss grammatical errors and are not Pearson's scoring engine or a full grammar assessment. Use this lesson to review the joins yourself; the PTE scoring guide explains the limits of practice estimates.
