C1 Advanced Writing Overview

The C1 Advanced Writing paper lasts 1 hour 30 minutes. You complete two tasks. Part 1 is always a compulsory essay. Part 2 gives you a choice between letter, proposal, report, or review. Each task should be 220-260 words. This is significantly longer than B2 First, giving you scope to develop detailed arguments.

Examiners assess your work on four criteria, each worth equal marks: Content (did you address all parts of the question?), Communicative Achievement (appropriate register and tone), Organisation (logical structure with cohesive devices), and Language (range of vocabulary and grammatical accuracy at C1 level).

Part 1: The Essay

The C1 Advanced essay is more demanding than B2 First. You will read a statement on an abstract or social topic with three bullet points. You must discuss two bullet points in depth and address the third more briefly. Use a formal academic register throughout.

Essay Structure:

  • Introduction (40-50 words): Paraphrase the topic, state your position, and outline the points you will discuss.
  • Body paragraph 1 (60-70 words): Discuss the first bullet point with a developed argument, example, and analysis.
  • Body paragraph 2 (60-70 words): Discuss the second bullet point, linking or contrasting it with the first.
  • Body paragraph 3 (30-40 words): Briefly address the third bullet point or offer a counterargument.
  • Conclusion (30-40 words): Summarise your position and offer a final thought or recommendation.

Model Essay

"Your class has discussed whether technology has improved the quality of education. Your teacher has asked you to write an essay discussing the benefits of technology in education and how it might affect the role of teachers. Include your own perspective."

The integration of technology into education has transformed how students access information and engage with learning materials. While the benefits are considerable, it is essential to consider how this shift affects the role of educators.

On one hand, technology offers unprecedented opportunities for personalised learning. Adaptive learning platforms, such as those used for language acquisition, can tailor content to each student's level and pace. Furthermore, online resources enable learners to access high-quality educational material regardless of their geographical location. This democratisation of knowledge is arguably one of the most significant developments in modern education.

On the other hand, the expanding role of technology does not diminish the importance of teachers. On the contrary, educators are needed now more than ever to guide students in evaluating sources, developing critical thinking skills, and navigating the vast amount of information available online. Technology should be viewed as a tool that enhances teaching rather than a replacement for it.

In my view, the most effective educational model combines technological resources with skilled human guidance. A student using an AI-powered language app, for instance, still benefits enormously from conversation practice with a tutor who can provide real-time correction and cultural context.

In conclusion, while technology has undoubtedly improved access to education, it complements rather than replaces the educator's role. The future of education lies in thoughtful integration of both.

Part 2: Letter

The letter task may be formal (to an editor, official, or organisation) or informal (to a friend or colleague). Read the task carefully to determine the required register. Formal letters require standard salutations, clear purpose statements, and formal closings.

Model Letter (Formal)

"You have seen an advertisement for a volunteer programme. Write a letter of application explaining why you are suitable."

Dear Hiring Manager,

I am writing to apply for the volunteer teaching position advertised on your website. I believe my qualifications and experience make me a suitable candidate for this role.

I recently graduated with a degree in English Literature and have been working as a part-time English tutor for the past two years. This experience has given me practical skills in lesson planning, classroom management, and adapting materials for learners at different levels. I am particularly experienced in working with teenage learners, which I understand is the target group for this programme.

In addition to my teaching experience, I have strong organisational skills. During my time at university, I coordinated a student-led language exchange programme involving over 50 participants. This taught me how to manage logistics, communicate effectively with diverse groups, and solve problems under pressure.

I would welcome the opportunity to contribute to your organisation and develop my skills further. Thank you for considering my application.

Yours faithfully,
Jane Mitchell

Part 2: Proposal

The proposal is unique to C1 Advanced. It involves making suggestions and recommendations for a future course of action. Use headings, persuasive language, and a clear structure. A proposal is more persuasive than a report, aiming to convince the reader to take action.

Model Proposal

"The director of your language school has asked for proposals on how to improve student motivation. Write a proposal with practical suggestions."

Proposal for Improving Student Motivation

Introduction

This proposal aims to address the decline in student motivation observed over the past six months. Based on feedback from students and teachers, the following recommendations are made.

Current Situation

Attendance rates have fallen by 15% compared to the previous term. The most common reason cited by students is a lack of engaging activities and limited opportunities to practise outside the classroom.

Recommendations

Firstly, implementing a weekly conversation club would give students regular speaking practice in a relaxed setting. This costs nothing and could be led by volunteer teachers. Secondly, introducing a reward system, such as a student-of-the-month certificate, would recognise effort and achievement. Finally, organising one monthly cultural event, such as a film screening or cooking class conducted in English, would make learning more relevant and enjoyable.

Expected Outcomes

These measures are expected to increase attendance by at least 10% within three months and improve overall student satisfaction.

Part 2: Report

A report presents information and findings from a survey, evaluation, or research. Use formal tone, section headings, and factual language. Include an introduction, findings, and recommendations.

Model Report

"Your company has asked you to evaluate the current staff training programme and suggest improvements."

Report on Staff Training Programme

Introduction

The purpose of this report is to evaluate the effectiveness of the current staff training programme. Data was collected through a staff survey with 45 responses and interviews with department heads.

Findings

Overall satisfaction with the training programme was rated at 6.2 out of 10. The main strengths identified were the quality of trainers and the relevance of technical content. However, 68% of respondents felt the sessions were too infrequent, and 52% reported difficulty applying the training to their daily work.

Recommendations

Based on these findings, I recommend the following: increase training frequency from quarterly to monthly, introduce follow-up sessions to reinforce learning, and include more practical case studies based on real workplace scenarios.

Part 2: Review

A review gives a critical opinion on a cultural product such as a film, book, exhibition, or TV series. Include both positive and negative aspects, support your opinions with specific examples, and end with a clear recommendation.

Model Review

"An online magazine has asked you to review a documentary you watched recently. Write a review explaining what you learned and whether you would recommend it."

My Octopus Teacher: A Masterclass in Connection

My Octopus Teacher, directed by Pippa Ehrlich and James Reed, is a remarkable documentary that explores the unlikely friendship between a filmmaker and a wild octopus off the coast of South Africa. Having watched it recently, I can see why it won an Academy Award.

The documentary follows Craig Foster as he free-dives in the kelp forest every day for a year. What makes the film exceptional is the intimate footage of the octopus's behaviour. Watching the creature camouflage itself, escape predators, and interact with its environment is genuinely fascinating. The film challenges the assumption that wild animals are indifferent to humans, showing moments of what appears to be mutual trust and curiosity.

However, the film is not without weaknesses. Some viewers may find the meditative pace slow, and the focus on Foster's personal journey occasionally overshadows the scientific aspects. A more detailed exploration of octopus intelligence from a biological perspective would have strengthened the documentary.

Despite these minor criticisms, My Octopus Teacher is a powerful and moving film. I would recommend it to anyone interested in nature, marine biology, or simply beautiful storytelling.

Advanced Grammar Checklist

At C1 level, examiners expect you to demonstrate a range of complex grammatical structures. Here are the key structures to include:

  • Inversion: "Not only does technology improve access, but it also..."
  • Conditionals (mixed and third): "Had the programme been implemented earlier, results would have improved sooner."
  • Passive structures: "It can be argued that..." / "It was decided that..."
  • Relative clauses (defining and non-defining): "The proposal, which was submitted last week, outlines several key improvements."
  • Cleft sentences for emphasis: "What makes this approach effective is its simplicity."
  • Subjunctive structures: "It is essential that every student have access to resources."
  • Modals of deduction: "This must have been considered before the decision was made."
  • Participle clauses: "Having analysed the data, the committee recommended..."

Common Mistakes

  • Underdeveloping ideas: At C1 level, you need to develop each point with examples and analysis. One sentence per point is not enough.
  • Inconsistent register: Switching between formal and informal within one task. Decide the register from the task type and maintain it throughout.
  • Weak linking: Using basic connectors (and, but, so) instead of sophisticated ones (furthermore, nevertheless, consequently, with regard to).
  • Repetitive vocabulary: At C1 level, repeating the same words suggests limited range. Use synonyms and paraphrase.
  • Forgetting the task type format: A proposal needs headings and persuasive language. A report needs findings and recommendations. Using the wrong format loses marks in Communicative Achievement.

Practice Questions

  1. Essay: "Should governments invest more in public transport or electric car infrastructure? Discuss."
  2. Letter: "Write a letter to the editor of a newspaper expressing your views on a local environmental issue."
  3. Proposal: "Propose a plan to reduce energy consumption in your workplace or college."
  4. Report: "Report on the effectiveness of remote working at your organisation."
  5. Review: "Review a television series you have watched recently for an online blog."
