DELE C2 Writing: examples and strategies

The writing component of the DELE C2 is part of Test 2 (Prueba 2), which lasts 150 minutes and integrates listening comprehension, reading comprehension and written expression into 3 tasks. This is where many candidates struggle most, because it demands not just language accuracy but the ability to synthesize information from multiple sources into coherent, well-structured formal texts.

If you are not yet familiar with the overall exam structure, start with our guide on what the DELE C2 is before diving into writing-specific strategies.

How Test 2 writing tasks work

In Test 2, you do not simply write an essay from scratch. Each task provides source materials—audio recordings, written texts, or both—that you must process and integrate into your written response. The tasks typically require you to:

• Summarize and synthesize information from multiple sources.
• Compare and contrast different viewpoints presented in the sources.
• Produce a specific text type (report, article, formal letter, essay) based on the input materials.
• Maintain appropriate register and tone for the specified genre.

The key challenge is that you must demonstrate comprehension of the sources while producing original, well-organized text—not simply copying or paraphrasing what you heard or read.

Text types you may encounter

The C2 writing tasks can ask for various formal text types:

Argumentative essay

Present a thesis, develop arguments with evidence from the sources, address counterarguments, and reach a conclusion. This is the most common format.

Formal report

Synthesize data from multiple sources into a structured report with clear sections, objective tone and recommendations.

Opinion article

Write a newspaper-style opinion piece that takes a clear position while engaging with the complexity of the topic.

Formal letter or complaint

Address a specific recipient with appropriate formality, clearly stating the purpose and supporting it with relevant information.

Structuring your text

Regardless of the text type, a strong C2 written response follows a clear structure:

Introduction (1 paragraph)

• Contextualize the topic briefly.
• State your thesis or the purpose of the text.
• Signal the structure that will follow (without being mechanical).

Development (2-4 paragraphs)

• Each paragraph develops one main idea.
• Integrate information from the sources naturally (do not simply list what each source says).
• Use discourse connectors to show relationships between ideas.
• Include your own analysis and critical perspective.

Conclusion (1 paragraph)

• Synthesize the main points without simply repeating them.
• Offer a final reflection, recommendation or forward-looking statement.
• End with impact—a strong final sentence that resonates.

Essential discourse connectors

At C2 level, examiners expect sophisticated use of connectors that go beyond basic linking words. Here are categories you should master:

• Additive: asimismo, por añadidura, cabe destacar que, en la misma línea.
• Adversative: no obstante, con todo, ahora bien, si bien es cierto que.
• Causal: dado que, en virtud de, habida cuenta de, puesto que.
• Consecutive: de ahí que, por consiguiente, en consecuencia, de modo que.
• Reformulative: dicho de otro modo, en otras palabras, esto es, a saber.
• Concessive: aun cuando, pese a que, a pesar de que, si bien.

Register and tone

The C2 demands formal academic register. This means:

• Avoid colloquial expressions and contractions.
• Use impersonal constructions: "se considera que..." rather than "yo creo que..."
• Employ nominalization: "la implementación de medidas" rather than "cuando implementan medidas."
• Use the subjunctive correctly in all its complex forms (pluperfect subjunctive, future subjunctive in fixed expressions).
• Vary sentence length and structure. Mix complex sentences with shorter ones for rhythm.

Common writing mistakes to avoid

Based on examiner reports, these are the most frequent errors in C2 writing:

Content mistakes

• Ignoring the source materials and writing a generic essay on the topic.
• Copying phrases directly from the sources instead of reformulating.
• Not addressing all parts of the task instructions.
• Failing to take a clear position when the task requires one.

Organization mistakes

• Writing without paragraph breaks or with paragraphs that are too long.
• Jumping between ideas without logical transitions.
• Including irrelevant information that does not serve the text's purpose.
• Writing an introduction that is too long relative to the development.

Language mistakes

• Incorrect use of ser/estar in abstract contexts.
• Preposition errors with complex verbal constructions.
• Overusing the same connectors (especially "además" and "sin embargo").
• Inconsistent register—mixing formal and informal language.

Practice strategy

To improve your writing for the C2, follow this weekly routine:

• Monday-Wednesday: Write one complete Test 2 response (timed at 50 minutes per task).
• Thursday: Review and self-correct using a checklist (structure, connectors, register, grammar).
• Friday: Rewrite the same text incorporating improvements.
• Weekend: Read model texts in your target genres to internalize structure and register.

If possible, get feedback from a qualified tutor who knows the DELE C2 assessment criteria. Self-correction is valuable but has limits—an experienced eye can catch register issues and structural weaknesses you might miss.

Time management in Test 2

With 150 minutes for 3 tasks, time management is critical:

• Allocate roughly 50 minutes per task.
• Spend the first 10 minutes of each task processing the source materials and planning your response.
• Write for 30-35 minutes.
• Reserve 5-10 minutes for revision and correction.

Never skip the planning phase. A well-planned text written in 30 minutes will score higher than an improvised text written in 45 minutes.
