DELF B1 writing test preparation guide covering French letters, emails, opinion responses, writing samples, and grammar tips.

DELF B1 Writing Test: Letters, Emails & Opinions

Writing in French at an intermediate level requires more than knowing grammar rules and memorising vocabulary. Candidates must understand the task, organise their ideas logically and communicate their message in a way that suits the reader. These skills become especially important when preparing for the DELF B1 examination.

The writing paper assesses whether candidates can express their thoughts, describe experiences, explain situations and give opinions in everyday contexts. Typical tasks may involve writing a personal letter, sending an email, making a complaint or presenting an argument about a familiar subject.

A clear structure makes these tasks easier to manage. Instead of writing sentences randomly, candidates can plan an introduction, develop their main points and finish with an appropriate conclusion. With regular practice, they can also learn to use linking expressions and grammatical structures more confidently.

This guide explains how to organise different types of French writing tasks, avoid common mistakes and prepare effectively for the examination. It also includes a practical example with an English translation to help learners understand how a well-organised response works.

Understanding the DELF B1 Writing Task

The DELF B1 examination measures intermediate French communication skills. In the writing section, candidates are expected to produce a written response that fulfils a specific purpose. They may need to express an opinion, describe a personal experience, explain a problem or respond to a situation.

The official examination format generally requires a written production of at least 160 words. Candidates should always check the current instructions and follow the word-count requirements provided for their examination.

Before writing, read the question carefully. Identify who will read the message, why it is being written and what information must be included. For example, an email to a friend can use a familiar tone, while a complaint to an organisation requires more formal language.

A strong response does not need complicated French in every sentence. Clear ideas, suitable vocabulary, correct basic grammar and a logical sequence are more useful than unnecessarily difficult expressions.

How to Structure a French Letter

Letters are common formats for communicating personal experiences, requests, opinions or complaints. The structure depends on the relationship between the writer and the recipient.

1. Begin with an appropriate greeting

Choose a greeting that matches the situation.

For an informal letter, you could use:

Cher Paul, — Dear Paul
Chère Marie, — Dear Marie
Salut ! — Hi!

For a formal letter, you could begin with:

Madame, Monsieur, — Dear Sir or Madam
Madame, — Dear Madam
Monsieur, — Dear Sir

Use the form that fits the task rather than choosing a greeting automatically.

2. Explain the purpose of the letter

The opening paragraph should make the reason for writing clear. If you are describing an experience, introduce the event. If you are making a complaint, briefly explain what happened. If you are expressing an opinion, introduce the subject.

Useful expressions include:

Je vous écris pour… — I am writing to you to…
Je voudrais vous parler de… — I would like to tell you about…
Je souhaite exprimer mon opinion sur… — I would like to express my opinion about…

3. Develop the main points

Use the middle paragraphs to address the requirements in the question. If the task asks you to describe an experience and explain your feelings, include both. If it requests a complaint and a solution, explain the problem and state what you expect.

Each paragraph should focus on one main idea. This prevents the letter from becoming confusing and makes it easier for the examiner to follow your message.

4. End the letter appropriately

An informal letter might end with:

À bientôt ! — See you soon!
Amicalement, — Best wishes
À très vite ! — See you very soon!

Formal letters require a more suitable closing. For example, Cordialement means “Kind regards” and is appropriate for many routine professional messages.

How to Write an Effective Email

Emails are useful for practising everyday communication because they can be formal, semi-formal or informal. The main challenge is choosing the correct tone while covering every point in the question.

Start with a suitable greeting, followed by a short opening that explains why you are contacting the recipient. Then organise the information into one or more paragraphs.

For instance, if you are writing to a friend about a French course, you might explain where you study, what you enjoy about the classes and whether you would recommend the course.

If the email concerns a practical issue, such as a cancelled event, explain the situation clearly and mention what action you would like the recipient to take.

Useful expressions include:

Je t’écris parce que… — I am writing to you because…
Je voudrais savoir si… — I would like to know whether…
Pourriez-vous me donner plus d’informations ? — Could you give me more information?
Merci pour votre réponse. — Thank you for your reply.
J’attends votre réponse. — I look forward to your reply.

Remember that tu is normally used for informal communication, while vous is used for formal or polite communication. Avoid switching between the two without a reason.

How to Structure an Opinion Response

Opinion-based tasks require candidates to state their position and support it with reasons. Merely saying that something is good or bad is not enough. You should explain why you hold that opinion and, where possible, provide an example.

A simple structure contains three parts.

Introduction

Introduce the topic and state your position.

Useful phrases include:

À mon avis,… — In my opinion…
Je pense que… — I think that…
Selon moi,… — According to me…

Main body

Give two or three relevant reasons to support your position. Explain each reason briefly and use examples where appropriate.

Linking expressions help organise your argument:

Tout d’abord — First of all
Ensuite — Next
De plus — Furthermore
Par exemple — For example
Cependant — However
En revanche — On the other hand

You do not need to include every possible argument. Select points that directly answer the question and explain them clearly.

Conclusion

Summarise your position in a final sentence. Avoid introducing a completely new argument at the end.

For example:

Pour toutes ces raisons, je pense que les transports publics sont importants dans une ville.

English translation: “For all these reasons, I think public transport is important in a city.”

Example: Giving an Opinion About Learning French Online

The following delf b1 writing sample demonstrates how to organise an opinion response using an introduction, supporting reasons and a conclusion.

Sujet (Topic): Pensez-vous qu’il est possible d’apprendre le français en ligne ? Expliquez votre opinion avec des exemples.

English translation: Do you think it is possible to learn French online? Explain your opinion with examples.

Exemple de réponse (Sample answer):

À mon avis, apprendre le français en ligne est une bonne solution pour les personnes qui ont un emploi du temps chargé. Aujourd’hui, il existe de nombreux cours et exercices sur Internet.

Tout d’abord, les cours en ligne permettent d’étudier à son propre rythme. Par exemple, un étudiant peut regarder une vidéo de grammaire plusieurs fois s’il ne comprend pas une règle. De plus, il est possible de pratiquer la compréhension orale en écoutant des podcasts ou en regardant des vidéos en français.

Cependant, apprendre seul peut parfois être difficile. Certaines personnes ont besoin de parler avec un professeur pour améliorer leur prononciation et corriger leurs erreurs. C’est pourquoi je pense qu’il est préférable de combiner les cours en ligne avec des conversations régulières.

Pour conclure, apprendre le français sur Internet peut être très efficace si l’on reste motivé et si l’on pratique régulièrement.

English translation:

In my opinion, learning French online is a good option for people with busy schedules. Today, there are many courses and exercises available on the Internet.

First of all, online courses allow students to learn at their own pace. For example, a student can watch a grammar video several times if they do not understand a rule. Furthermore, it is possible to practise listening comprehension by listening to podcasts or watching videos in French.

However, studying alone can sometimes be difficult. Some people need to speak with a teacher to improve their pronunciation and correct their mistakes. That is why I think it is better to combine online lessons with regular conversations.

To conclude, learning French on the Internet can be very effective if you stay motivated and practise regularly.

This example demonstrates a straightforward argument, supporting reasons, a practical example and a conclusion. Candidates can use the same organisational approach for other familiar topics, such as public transport, environmental protection, technology or healthy habits. They should adapt the content to the actual question rather than memorising the sample word for word.

Grammar and Vocabulary Tips for Better Writing

Good organisation should be supported by accurate language. At B1 level, candidates should pay attention to the following areas.

Verb tenses: Use the present tense for general opinions, the passé composé to describe completed events and the imparfait for background details or past habits. The future tense can be useful when discussing plans or possible consequences.

Agreement: Check whether adjectives agree with the nouns they describe. For example, une activité intéressante means “an interesting activity,” while des activités intéressantes means “interesting activities.”

Sentence variety: Combine simple sentences with a few longer sentences using parce que (because), mais (but), quand (when) and si (if). Avoid making every sentence extremely long.

Connecting ideas: Use linking expressions naturally to show contrast, sequence, cause and conclusion. Repeating the same expression in every paragraph can make the response sound mechanical.

Vocabulary: Learn useful expressions by topic. For example, environmental topics may involve la pollution (pollution), les déchets (waste) and protéger l’environnement (to protect the environment).

The goal is to communicate clearly rather than demonstrate every grammar rule in a single response.

Common Mistakes to Avoid

One frequent mistake is ignoring part of the question. Before writing, underline the instructions and check that every requested point is covered.

Another problem is using an inappropriate tone. A message to a friend should not sound like a formal business letter, while a complaint to an organisation should remain polite and professional.

Candidates sometimes write too little because they focus only on the main idea. Others write lengthy paragraphs that include unrelated information. A brief plan can help maintain the right balance.

Do not spend all your time drafting without reviewing your work. Leave a few minutes to check verb conjugations, agreements, spelling, punctuation and the overall organisation.

Finally, avoid translating complicated English sentences word for word into French. Build sentences using French structures that you understand and can apply correctly.

How to Practise Before the Examination

Regular writing practice is more effective than attempting several tasks only in the final week. Choose familiar subjects and practise different formats, including personal emails, formal letters, complaints and opinion paragraphs.

Use a timer to become comfortable planning, writing and reviewing a response within the available examination time. After finishing, check whether you have answered the question, organised your ideas and used an appropriate tone.

You can also maintain a vocabulary notebook containing linking expressions, useful sentence starters and common grammar corrections. Rewrite older responses after identifying mistakes to understand how your writing can improve.

When reviewing a DELF B1 writing sample, focus on its structure and language choices rather than copying the entire answer. Try writing about the same topic using different reasons and examples. This develops flexibility and prepares you for unfamiliar questions.

Conclusion

Success in the DELF B1 writing section depends on communicating ideas clearly, responding to the task and organising information logically. Letters require an appropriate greeting, a clear purpose and a suitable closing. Emails need a tone that matches the recipient, while opinion responses should present a position supported by reasons and examples.

Candidates preparing for the delf b1 writing test should practise different formats, review their grammar and learn useful linking expressions. Reading examples can provide guidance, but developing the ability to express personal ideas is equally important.

With consistent practice, careful planning and a final review of each response, learners can become more confident in written French and improve their ability to handle a range of examination topics.
