Cambridge IGCSE English as a Second Language tests how well you communicate in English: understanding what you read and hear, and expressing yourself in writing and speech. This guide maps the skills, shows a sensible study order and points out where students usually get stuck.
Which code is this subject?
There are two separate codes: 0510 and 0511. They share the same broad aim, which is practical communication, but the speaking test is handled differently. In 0510 the speaking test is an oral endorsement, reported separately. In 0511 the speaking test counts towards the grade.
Components, weightings, timings and speaking arrangements change between exam years. We do not list them here, because a guess could send you to the wrong plan. Read the current page for your code on Cambridge: 0510 and 0511 guides on this site explain what to check, and the syllabus and exam-year navigator helps you find the right page. Your school or exam centre confirms your entry, and handles registration and results.
Do not choose a code by nationality or by which one a friend takes. The entry you are given decides it. Never treat scores from the two routes as equivalent.
How is the subject built?
Think of four skills that feed each other:
- Reading: finding specific information, following main ideas, and working out meaning from context.
- Listening: catching detail, including corrections, and understanding a speaker’s attitude.
- Writing: emails, articles, reviews and reports that cover every point, suit the reader and stay organised.
- Speaking: interacting, extending answers and organising what you say.
Underneath them sit language tools: grammar that keeps meaning clear, sentence building, paraphrase, and accurate spelling and punctuation. Good marks rarely come from one skill in isolation. A student who reads the task carefully and hears corrections has far more to say and write.
A small example: two checks on one task
An original notice reads: The workshop has moved from Tuesday to Thursday. Bring your own laptop, but not a charger, as the room has sockets. Sign up by Monday.
Check for comprehension: On which day is the workshop now held? (Thursday.) What must you bring? (A laptop, not a charger.) By when do you sign up? (Monday.)
Check for expression: Write two sentences to a friend telling them what to bring and when to sign up. A good answer is “Please bring your laptop, but leave the charger at home. You need to sign up by Monday.”
Keep the two checks apart.
If you write “Tuesday”, that is a reading slip. If you know the facts but your sentences are muddled, that is an expression problem. Each needs a different repair, and mixing them hides the cause. This habit of separating understanding from expression runs through the whole guide.
In what order should you study the topics?
This is the order we suggest. You can skip what you already do well.
Start here
- 0510 and 0511 route awareness: confirm your code and exam year before choosing which tasks to practise.
Reading
- Reading for specific information: scanning notices for conditions, dates and deadlines, and handling distractors.
- Reading for main ideas: purposes, headings and the difference between an example and a claim.
- Vocabulary and inference: working out meaning, attitude and reference from context.
Listening
- Listening for detail: numbers, units, sequences and corrected details.
- Listening for viewpoint: opinion, agreement and changes of mind.
Language tools
- Grammar for clear meaning: tense, articles, agreement, linking and modal verbs.
- Sentence building and paraphrase: combining sentences and restating ideas accurately.
- Spelling, punctuation and proofreading: catching slips one issue at a time.
Writing
- Email communication: covering every point with suitable formality.
- Articles and reviews: organising description and judgement for a reader.
- Reports and extended responses: structuring findings and suggestions in balanced language.
Speaking
- Speaking interaction: extending answers and asking for clarification.
- Speaking organisation: structuring a personal example and connecting causes and consequences.
Confidence and transfer
- Language confidence and transfer: preparing questions, rehearsing with meaning and planning repeat attempts.
Reading and listening come first because they supply the language you later write and say. The language tools come before writing so that accuracy supports the tasks. Speaking is taught after writing, but it is worth starting a little speaking practice early, because confidence takes time.
How should you study it well?
Use a simple cycle: attempt, check, find the cause, repeat.
- Attempt before looking. Try a reading or listening task cold. Then check the explanation.
- Name the cause of each error. Was it a reading slip, a missed detail, a distractor, a language error or an organisation problem?
- Keep a correction list. Write your own repeated errors in one place. The lesson on creating a personal correction list shows how.
- Record your speaking. Listening to yourself shows pace, order and gaps. See self-reviewing pace.
- Use the original practice sets. The practice hub has questions and explained answers. The terminology page clears up confusing terms.
For help building a plan, see the study route guide and the revision guide. The summary selection and paraphrase studio and the writing revision compare view support practice at home, and they store nothing on our servers.
Where do students usually get stuck?
Some difficulties come up again and again. Each has a clinic page with a first repair:
- I understand the text but choose a distractor
- I miss corrected details in listening
- My email misses one of the required purposes
- I answer briefly but cannot develop a speaking response
- I use memorised phrases that do not fit the task
- I confuse 0510 and 0511 guidance
Many of these are habits and not lack of vocabulary. A habit can be changed with a few careful repetitions.
What does individual tuition add?
Self-study is enough for some students, and the guide to considering tuition explains when. One-to-one teaching helps when the same problem keeps returning, especially in writing and speaking, where you need someone to listen and respond.
A teacher can see your actual answer, separate what you understood from what you expressed, and have you repair the weak part while they watch. Your work stays yours, and entries and speaking test arrangements stay with your exam centre and Cambridge. If you would like to try it, see online one-to-one English as a Second Language tuition for how the paid one-hour trial works, and the guide to choosing a first lesson focus to get the most from it.
