Cambridge B2 First Certificate Writing Guide

The B2 First Writing paper has 2 parts. You must complete both tasks in 1 hour 20 minutes. Part 1 is compulsory and Part 2 offers a choice of tasks. The paper carries 20% of the total exam marks.

About the B2 First Writing Paper

The Writing paper tests your ability to produce two different pieces of writing. You must write between 140 and 190 words for each task. Both tasks carry equal marks.

In the past, the B2 First exam included an optional question on a set text, but this was removed in the 2015 revision. Today, both parts focus on practical, everyday writing tasks.

Paper Format

  • Parts: 2 tasks (both compulsory)
  • Duration: 1 hour 20 minutes
  • Word count: 140–190 words per task
  • Marks: 20% of total exam score

Time Management

  • Part 1 (Essay): About 40 minutes — allow 5 minutes for planning and 5 for checking
  • Part 2 (Choice): About 40 minutes — same planning and checking time

You should aim to write slightly above the minimum word count (around 160–180 words), but going significantly over 190 words can lead to losing focus and making more errors. Quality matters more than quantity.

Part 1: Compulsory Essay

About This Section

Part 1 is always an essay. You are given a title and two ideas related to the topic. You must write an essay that discusses both ideas and gives your own opinion. You may also include your own idea if you wish.

The essay is usually on a topic relevant to everyday life — for example, the environment, education, technology, or health. You do not need specialist knowledge.

You must write 140–190 words.

Technique for Part 1

Read the task carefully. Underline the topic and the two ideas you must discuss.

Plan your essay before you start writing. Decide which idea you agree with more, or whether you want to present a balanced argument.

Use a clear structure:

  • Introduction: Introduce the topic in 1–2 sentences. Don't copy the question word for word.
  • Body paragraph 1: Discuss the first idea with a reason or example.
  • Body paragraph 2: Discuss the second idea with a reason or example.
  • Conclusion: Give your overall opinion in 1–2 sentences.

Check your work. Look for spelling, grammar, and punctuation errors.

Extra Tips for Part 1

Use linking words to connect your ideas: However, On the other hand, Furthermore, In addition, As a result, In conclusion.

Avoid very informal language. The essay should be written in a neutral to semi-formal register.

Don't just list points — develop each idea with a reason, example, or explanation.

You can add a third idea of your own, but only if you have space. Don't sacrifice the development of the two required ideas.

Avoid starting every sentence with "I think". Vary your sentence structures to demonstrate range.

Part 2: Choice of Task

About This Section

In Part 2 you choose one task from three options. Each option specifies a different text type and situation. The possible text types are:

  • Article — for a magazine, newsletter, or website
  • Email/Letter — formal or informal, depending on the situation
  • Report — usually for a teacher, employer, or organisation
  • Review — of a book, film, restaurant, product, etc.

You must write 140–190 words. Read all three options before choosing — pick the one where you feel most confident about the topic and text type.

Technique for Part 2

Read all three options before you decide. Don't rush into the first one.

Ask yourself: Do I know enough vocabulary for this topic? Am I comfortable with this text type?

Identify the target reader. Who are you writing to? This determines your register (formal, neutral, or informal).

Cover all the content points. Each task gives you specific things to include. Missing a content point will cost you marks.

Use an appropriate layout. For example, a letter needs an opening and closing; a report may use headings.

Extra Tips for Part 2

Match your tone to the situation. An email to a friend is informal; a report for your manager is formal.

Don't write a list of bullet points unless the text type calls for it (like a report). Most tasks expect connected prose.

Use paragraphs. Even in shorter texts, clear paragraphing shows good organisation.

If you choose a review, remember to give your recommendation at the end — would you recommend it or not?

B2 First Writing Text Types

Essay (Part 1 only)

Register: Neutral to semi-formal

Structure: Introduction, 2–3 body paragraphs, conclusion

Key features: Clear opinion, developed arguments, linking words, no bullet points or headings

Common mistake: Writing too informally or simply listing ideas without developing them

Article

Register: Semi-formal to informal — engaging and interesting to read

Structure: Eye-catching title, engaging opening, 2–3 paragraphs, strong ending

Key features: Addresses the reader directly ("Have you ever...?"), rhetorical questions, personal opinions and anecdotes

Common mistake: Writing it like an essay. An article should feel lively and personal.

Email / Letter

Register: Depends on who you're writing to — informal for a friend, formal for a company or authority

Structure: Greeting, clear paragraphs addressing each point, appropriate sign-off

Key features: Appropriate opening (Dear Sir/Madam vs Hi/Hello), reason for writing in the first paragraph, all content points addressed

Common mistake: Mixing registers — don't use "Hey" in a formal letter or "I am writing to inform you" in an email to a friend

Report

Register: Formal to semi-formal

Structure: Headings for each section, introduction stating the purpose, sections with findings, conclusion with recommendations

Key features: Objective tone, factual language, clear recommendations, headings and subheadings

Review

Register: Semi-formal to informal

Structure: Brief introduction of what you're reviewing, description, your opinion, recommendation

Key features: Mix of description and opinion, adjectives and descriptive language, clear recommendation at the end

Common mistake: Only summarising the plot or content without giving your personal evaluation

How B2 First Writing Is Marked

Each task is marked on a scale of 0–5 across four criteria. Both examiners' marks are combined to produce your final Writing score, which is reported on the Cambridge English Scale (typically 140–190 for B2).

The Four Criteria

Criterion What examiners look for
Content Have you addressed all the content points in the task? Is the content relevant to the target reader?
Communicative Achievement Is the writing appropriate for the text type? Does it hold the reader's attention? Is the register suitable?
Organisation Is the text well-organised with clear paragraphs? Are ideas linked logically? Is there a clear beginning, middle, and end?
Language Is there a good range of vocabulary and grammar? Are errors minor and infrequent? Is the language appropriate for B2 level?

What Gets Top Marks (Band 5)

  • All content points are fully addressed and the effect on the reader is very positive
  • The conventions of the text type are used effectively to hold the reader's attention
  • The text is well-organised with a variety of cohesive devices
  • A wide range of vocabulary and grammar is used with full flexibility and accuracy

Common Reasons for Low Marks

  • Missing content: Not addressing all parts of the task
  • Wrong text type: Writing an essay when asked for an article, or vice versa
  • Wrong register: Being too informal in a report, or too formal in a friendly email
  • Under the word count: Writing fewer than 140 words usually means content points are missing
  • Poor organisation: No clear paragraphs, no introduction or conclusion
