Write & Improve: Free Cambridge Writing Feedback

Instant feedback only helps when it changes your next draft

Write & Improve is useful because it shortens the distance between writing a text and receiving a response. That speed can support frequent practice, but the feedback itself is not the learning outcome. The useful part is the decision you make next: what you rewrite, what you record, and what you test again under timed conditions.

This guide treats the tool as one component in a Cambridge C1 or C2 writing workflow. It does not treat an automated response as an official exam grade, a substitute for Cambridge assessment criteria, or a replacement for a teacher who can judge argument quality and task fulfilment in context.

Is Write & Improve free, and what do you get?

Yes. Cambridge describes the core platform as a free online tool. You can choose a task or upload writing, receive an estimated CEFR level, inspect word- and sentence-level feedback, revise the text, and watch progress over time. Cambridge's help centre says the free offer includes more than 250 tasks across A1-C2; Test Zone and Class View are optional products with additional paid features.

That distinction matters. The free feedback is designed for repeated practice, not as an official Cambridge mark or a prediction of your exam result. Start with the free workflow, and only consider a paid feature if it solves a specific need such as teacher class management or authentic test material.

What should you use Write & Improve for?

The platform is most effective for repeatable practice where you control the variables. Good uses include:

• writing the same genre several times across different prompts
• identifying grammar or wording patterns that recur across drafts
• comparing a first version with a deliberate rewrite
• practising between longer teacher-led sessions
• testing whether a correction remains accurate in a new paragraph

It is less useful when you submit unrelated texts, glance at the response, and immediately move to a new topic. That produces activity without a reliable revision cycle.

What should you not expect from automated feedback?

Automated feedback can point you towards language patterns, but it cannot fully determine whether an idea is convincing, whether evidence is well chosen, or whether a response handles every implication of a complex task. At C2, especially, a grammatically correct sentence may still be weak because its register, emphasis, or rhetorical effect is inappropriate.

Keep three limits in mind:

1. A tool response is not an official Cambridge result.
2. A suggested correction may improve local grammar without improving the whole text.
3. Higher-level writing requires judgement about audience, purpose, organisation, and effect—not only error removal.

Use the linked official Cambridge and CEFR sources below when you need current definitions of level or exam criteria.

What is the best five-stage workflow?

1. Establish a clean baseline

Choose one realistic task and write it under the conditions you want to improve. If you are practising exam performance, set a time limit, respect the required genre, and avoid dictionaries or rewriting tools during the first draft. Save that original version before submitting it.

The baseline matters because otherwise you cannot distinguish genuine improvement from extra help received during drafting.

2. Classify feedback instead of accepting it blindly

Sort each useful comment into a small number of categories:

Do not create an enormous error log. Record patterns that appear more than once or that materially affect clarity.

3. Rewrite the whole affected passage

Correcting one highlighted word is often too shallow. Rewrite the sentence, then reread the paragraph around it. If the problem concerns organisation or register, rewrite the full paragraph or opening rather than making a cosmetic substitution.

Keep the first and second versions side by side. Ask what changed and why. A revision is useful only if you can explain the principle behind it.

4. Transfer the correction to a new task

Two or three days later, write a different prompt in the same genre. Deliberately reuse the corrected structure or collocation in a new context. This checks transfer: whether the improvement has become active knowledge rather than a remembered correction tied to one text.

For example, if a report repeatedly uses informal recommendations, practise two new recommendation paragraphs with controlled formal language. If an essay overuses simple linkers, revise paragraph transitions in a new argument.

5. Add periodic human or rubric-based review

After several automated cycles, review a complete text against the official writing criteria or ask a qualified teacher to evaluate it. This is where you check questions that automated feedback may underweight: Did the response answer the exact task? Is the argument sufficiently developed? Does the genre feel authentic? Is the register consistent from beginning to end?

How should C1 and C2 candidates use it differently?

At C1 Advanced, the largest gains often come from dependable control: clear paragraphing, accurate complex sentences, relevant development, and consistent register. Feedback should help you reduce repeated errors without making the prose stiff or memorised.

At C2 Proficiency, accuracy is only the baseline. Revision should also improve precision, flexibility, information flow, and rhetorical effect. Instead of merely replacing a common word with a rare one, ask whether the new choice is more exact and natural for the audience.

How can you connect feedback to Cambridge writing criteria?

Use a four-column review after every second or third draft:

• Content: mark the exact sentence or paragraph that answers each task point.
• Communicative achievement: identify audience, purpose, and genre conventions.
• Organisation: outline the function of each paragraph and the links between them.
• Language: select two successful choices and two recurring limitations.

This prevents grammar feedback from dominating the review. A polished response can still underperform if it does not fulfil the task or communicate appropriately.

What does a useful error log look like?

A compact log should be actionable. Record the original phrase, the corrected version, the reason, and one new example. Avoid entries such as “grammar” or “vocabulary”; they are too broad to guide the next session.

Example:

Review the log before writing, not only after. Choose one or two patterns as targets for the next draft.

How often should you submit writing?

Frequency should leave room for revision. Three complete first drafts in one evening are usually less useful than one draft, one careful rewrite, and one transfer paragraph later in the week.

A practical weekly rhythm is:

1. Day 1: timed first draft and initial feedback classification
2. Day 2: full rewrite plus error-log examples
3. Day 4: new prompt in the same genre
4. Day 6: rubric review or teacher feedback on one selected text

Repeat the cycle for four weeks before judging whether a genre has improved.

How do you measure progress without trusting one score?

Track behaviours and outcomes together:

• number of task points fully covered
• repeated error categories per 100 words
• time needed to plan and proofread
• consistency of register
• whether corrections transfer to a new prompt
• periodic teacher or rubric judgement

A rising automated score can be encouraging, but transfer and task fulfilment are stronger evidence that your writing is becoming more reliable.

When should you use a teacher instead?

Seek human review when you cannot explain contradictory feedback, when your writing is accurate but scores have plateaued, or when you need judgement about argument, genre, and rhetorical effect. Teacher feedback is especially valuable near an exam date because it can prioritise the one or two limitations most likely to affect performance.

You can use the Practice English Writing Lab for additional structured practice, but the same limitation applies: AI-assisted feedback is guidance, not official marking.

Final takeaway

Write & Improve works best as a fast mirror inside a slower learning process. Preserve the first draft, classify the response, rewrite meaningfully, transfer the correction, and periodically check the whole text against official criteria. The rewrite—not the submission—is where most of the durable learning happens.
