The O-Level English Editing section may be short, but it should not be underestimated. These 10 marks can make a meaningful difference to a student's Paper 1 result, especially when every mark counts towards the final English grade.
Students are required to identify grammatical errors in a connected passage and replace them with the correct words. Although the task may appear straightforward, many students lose marks because they rely only on whether a sentence "sounds right", examine each line in isolation or change words without understanding the grammar rule involved.
Achieving full marks requires more than a good instinct for English. Students need a strong foundation in grammar, familiarity with common error patterns and a systematic way to check the passage.
In this O-Level English Editing guide, we will explain what the section tests, the common errors students should prepare for and a step-by-step method they can use to improve their accuracy.
What Is the O-Level English Editing Section?
Editing is Section A of O-Level English Paper 1 and carries 10 marks. Paper 1 lasts 1 hour and 50 minutes, carries 70 marks and accounts for 35% of the overall English Language examination result.
Students are given a continuous prose passage of no more than 250 words. They must identify grammatical errors and write the appropriate corrections in the spaces provided. The official 2026 syllabus also states that spelling and punctuation errors are not tested in this section.
This means students should focus on whether the words in the passage are grammatically and logically appropriate.
Errors may involve areas such as:
- subject-verb agreement;
- verb tense and verb forms;
- singular and plural nouns;
- articles and determiners;
- adjectives and adverbs;
- pronouns;
- prepositions;
- connectors;
- comparison; and
- fixed grammatical expressions.
Students should always read the instructions printed on the examination paper carefully before beginning the task.
Why Do Students Lose Marks in O-Level Editing?
Many students understand basic grammar rules but struggle to recognise when those rules have been broken in a connected passage.
Here are some common reasons marks are lost.
Students read each sentence in isolation
Some grammatical mistakes can only be detected by considering information from an earlier sentence.
For example:
Last Saturday, my classmates and I visited an animal shelter. We clean the cages and prepared food for the animals.
The word "clean" may be grammatically correct in another context. However, the phrase "Last Saturday" establishes that the actions happened in the past.
The correct sentence is:
We cleaned the cages and prepared food for the animals.
Students must therefore understand the overall time frame of the passage rather than checking each verb separately.
Students rely only on whether a sentence sounds natural
Reading widely can help students develop a useful instinct for English. However, instinct alone is not always reliable.
Incorrect expressions may sound familiar because students have heard them used in casual conversation. At the same time, a correct formal construction may sound unusual because they encounter it less frequently.
Students should be able to explain the grammar rule behind each correction.
Students change words that are already correct
When students cannot immediately find an error, they may start replacing words that sound unusual.
Editing is not a rewriting exercise. Students should not change a word simply because another expression sounds more sophisticated.
A correction should only be made when there is a clear grammatical or logical problem.
Students recognise the error but choose the wrong correction
A student may correctly notice that a verb is wrong but replace it with another unsuitable form.
For example:
The equipment was damage during delivery.
Changing "damage" to "damaging" would still be incorrect. The passive construction requires the past participle:
The equipment was damaged during delivery.
Students must identify both the error and the exact grammatical form required.
Students do not reread the corrected passage
A replacement word may appear correct on its own but fail to fit the complete sentence.
After making a correction, students should reread the entire sentence and, finally, the entire passage.
A Step-by-Step Method for O-Level English Editing
Instead of searching randomly for mistakes, students can follow a structured checking process.
Step 1: Read the Entire Passage for Meaning
Begin by reading the complete passage once without rushing to make corrections.
Identify:
- who or what the passage is about;
- when the events take place;
- whether it describes past events, current routines or general truths;
- how the ideas progress; and
- what each pronoun refers to.
Understanding the meaning gives students the context needed to recognise errors.
Some mistakes may not appear obvious until the entire passage has been read.
Step 2: Establish the Main Time Frame
Determine whether the passage mainly uses:
- the present tense;
- the past tense;
- the future tense; or
- a suitable combination of tenses.
Students should not assume that every verb must use the same tense. A passage can move between tenses when the meaning requires it.
For example:
During our visit last week, the guide explained that dolphins are highly intelligent animals.
"Explained" is in the past tense because the visit occurred last week.
"Are" remains in the present tense because dolphin intelligence is presented as a general truth.
The aim is not to make every verb identical. Each verb should suit the time and meaning of its clause.
Step 3: Check the Verbs
Verbs are a useful place to begin because several types of grammatical errors may occur.
For every verb, ask:
- What is the subject?
- Is the subject singular or plural?
- When does the action happen?
- Does another verb determine its form?
- Should the sentence use the active or passive voice?
Students should check:
- subject-verb agreement;
- tense;
- auxiliary verbs;
- modal verbs;
- infinitives;
- gerunds;
- participles; and
- active and passive constructions.
Step 4: Check Nouns, Articles and Determiners
Next, examine the noun phrases.
Ask whether:
- a countable noun should be singular or plural;
- a singular countable noun has an appropriate determiner;
- an uncountable noun has been treated correctly;
- "a", "an" or "the" is required; and
- quantity words match the type of noun.
For example:
The programme gave the participants many useful advice.
"Advice" is uncountable and should not be used after "many".
A grammatically suitable correction would be:
The programme gave the participants much useful advice.
Students must pay attention to words such as:
- many and much;
- fewer and less;
- several and each;
- a few and a little; and
- these and this.
Step 5: Check the Word Forms
Determine whether each sentence requires a:
- noun;
- verb;
- adjective; or
- adverb.
For example:
The volunteers worked tireless throughout the afternoon.
The word describes how the volunteers worked. An adverb is required:
The volunteers worked tirelessly throughout the afternoon.
Students should ask what the word is describing.
- An adjective commonly describes a noun.
- An adverb commonly modifies a verb, adjective or another adverb.
- A noun may follow a determiner or preposition.
- A verb expresses an action, occurrence or state.
Step 6: Check Pronouns and References
Every pronoun should refer clearly to an appropriate noun.
Check words such as:
- he;
- it;
- they;
- her;
- their;
- these; and
- those.
For example:
The organisers placed several recycling bins near the entrance because it was easily accessible.
The pronoun refers to the plural noun "bins".
The correct sentence is:
The organisers placed several recycling bins near the entrance because they were easily accessible.
Students should also ensure that a pronoun does not have two possible references.
Step 7: Check Prepositions and Fixed Expressions
Some words are regularly used with particular prepositions.
Useful expressions include:
- interested in;
- responsible for;
- participate in;
- contribute to;
- depend on;
- capable of;
- familiar with; and
- prevent someone from doing something.
For example:
The students participated at a community clean-up.
The correct expression is:
The students participated in a community clean-up.
Prepositions are best learnt as part of complete expressions rather than as isolated words.
Step 8: Check Connectors and Logic
Connectors must show the correct relationship between ideas.
Common relationships include:
- addition;
- contrast;
- cause;
- result;
- purpose;
- condition; and
- concession.
For example:
The path was steep and slippery, so the hikers refused to give up.
The word "so" suggests that the difficult conditions caused the hikers to continue, which is not the intended relationship.
The correct connector is:
The path was steep and slippery, but the hikers refused to give up.
The second clause contrasts with what the reader might expect.
Step 9: Reread the Corrected Passage
Finally, read the passage again from beginning to end.
Do not look only at the words you changed.
Check whether:
- the timeline remains consistent;
- the pronouns have clear references;
- the sentences are grammatically complete;
- the connectors make logical sense; and
- the complete passage reads smoothly.
This final reading can reveal mistakes that were missed during the earlier checks.
A Useful Checking Order to Remember
Step | Check | What to Look For |
|---|---|---|
1 | Meaning | Understand what the passage is saying |
2 | Time | Identify the main time frame and tense |
3 | Verbs | Agreement, verb forms and active/passive voice |
4 | Nouns | Number, articles, determiners and countability |
5 | Word forms | Nouns, verbs, adjectives and adverbs |
6 | References | Pronouns and relative pronouns |
7 | Relationships | Prepositions, connectors and logical links |
8 | Final reading | Reread the corrected passage from beginning to end |
