Write About an Important Decision B1 Writing Practice Tests Rules & Examples

How to Write About an Important Decision in English

Every day, we make choices — some small, some life-changing. Writing about an important decision means explaining what the decision was, why you made it, and what happened as a result. This type of writing appears in Cambridge B1 Preliminary tasks as a short article for a school magazine or website, or as a personal narrative story. It is a chance to show your ability to organise ideas clearly, use a variety of tenses, and connect your sentences with intermediate linking words.

Real-life examples of important decisions include choosing a school subject, moving to a new city, starting a new hobby, or deciding to learn a new language. Whatever the topic, the key is to make your writing engaging, personal, and well-structured.

Essential Writing Rules and Sentence Structure

1. Use Three or Four Clear Paragraphs

A well-organised B1 text always has a clear structure. For writing about an important decision, use this plan:

• Paragraph 1 — Introduction: Introduce the decision and when you made it.
• Paragraph 2 — Reasons: Explain why you made this decision.
• Paragraph 3 — Result: Describe what happened as a result and how you felt.
• Paragraph 4 — Conclusion: Give your personal opinion or recommendation.

2. Use Narrative Past Tenses Accurately

When writing about a past decision, you need to combine three past tenses naturally:

• Past simple — for completed actions: I decided to change schools.
• Past continuous — for background situations: I was feeling unhappy at my old school.
• Past perfect — for events that happened before another past event: By the time I made my decision, I had already spoken to my parents.

3. Build Complex Sentences with Relative Clauses

Relative clauses make your writing more sophisticated. Connect ideas using who, which, that, and where.

• My teacher, who had always encouraged me, was very supportive.
• It was a decision that changed my life completely.
• I moved to a new school where I quickly made new friends.

4. Use Conditionals to Reflect on Your Decision

Second conditionals are perfect for reflecting on past decisions:

• If I had not made that decision, I would never have discovered my passion for art.
• If I were in the same situation today, I would make exactly the same choice.

5. Punctuate Linking Words Correctly

When a linking adverb such as However, Therefore, or In addition starts a sentence, always place a comma directly after it.

• However, I was not sure it was the right choice at first.
• Therefore, I talked to my family before doing anything.
• In addition, I had to think carefully about the future.

Useful Linking Words (Connectors)

Use these connectors to join your ideas naturally and show the examiner that you can write at B1 level. Pay close attention to the differences between them.

Model Text

[TITLE] The Best Decision I Ever Made

[Paragraph 1 — Introduction: What was the decision and when?]
Two years ago, I made a decision that completely changed my life. Although I had been studying science at school, I decided to switch to the arts programme, which focused on music and drama. It was not an easy choice to make.

[Paragraph 2 — Reasons: Why did you make this decision?]
I had always loved performing, even though I had never had the confidence to pursue it seriously. While I was thinking about my future, I realised that science simply did not make me happy. Therefore, I spoke to my parents and my teacher so that I could get some honest advice before deciding.

[Paragraph 3 — Result: What happened? How did you feel?]
As soon as I joined the new programme, I felt a huge sense of relief. In addition, I quickly made friends who shared my interests. As a result, my confidence grew enormously.

[Paragraph 4 — Conclusion: Opinion and recommendation]
If I were in the same situation today, I would make exactly the same choice. I would definitely encourage anyone who is unsure about their future to follow their passion — it is always worth it.

Model Text Annotations

• Title: Catchy and personal — immediately tells the reader what the text is about.
• Paragraph 1: Uses past simple (decided) and past perfect (had been studying) to set the scene. Includes a relative clause (which focused on music and drama).
• Paragraph 2: Uses even though, while, therefore, and so that to connect ideas. Uses past continuous (was thinking) for background context.
• Paragraph 3: Uses as soon as and in addition and as a result to show sequence and consequence.
• Paragraph 4: Uses a second conditional (If I were... I would) and a modal for advice (I would definitely encourage) for a strong, engaging conclusion.

Common Writing Mistakes to Avoid

Study these common B1 mistakes carefully. Can you see why each incorrect example is wrong?

❌ Although the decision was difficult, however I felt confident about it.
✅ Although the decision was difficult, I felt confident about it.
Never use although and however together in the same sentence. They both show contrast, so you only need one. Use although within a single sentence, or start a new sentence with However, followed by a comma.

❌ However I was nervous, I decided to go ahead with my plan.
✅ However, I was nervous, so I thought carefully before making my final decision.
However cannot introduce a subordinate clause the way although can. It must start a new sentence and be followed by a comma. Use although or even though if you want to contrast within one sentence.

❌ Despite I was afraid, I applied for the new job.
✅ Despite my fear, I applied for the new job.
Despite must be followed by a noun, a pronoun, or a gerund (-ing form) — never by a subject and verb. Compare: Despite feeling afraid / Despite my fears ✅ vs Despite I was afraid ❌.

❌ While I was thinking about my future, I realise that science didn't make me happy.
✅ While I was thinking about my future, I realised that science did not make me happy.
Do not mix tenses without reason. If you are narrating a past event, keep all main verbs in the past tense. Switching to the present tense (realise) mid-narrative is a tense-shifting error that will cost you marks.

❌ It was definately the right choise, and I felt very confortable with my desision.
✅ It was definitely the right choice, and I felt very comfortable with my decision.
Watch the spelling of these commonly misspelled B1 words: definitely, choice, comfortable, decision. Practise writing them correctly every time.
