B2 First mistakes: 12 to avoid in every paper
The B2 First mistakes that cost the most marks are rarely about difficult grammar. They are habits: leaving answers blank, ignoring word limits, writing the wrong text type, choosing Listening answers because you heard a matching word, and giving short answers in Speaking. This post, part of the B2 First blog, goes through twelve of them, paper by paper, with a fix for each.

Why small mistakes matter so much
Your overall B2 First result is the average of five scores: Reading, Use of English, Writing, Listening and Speaking. There is no minimum score in each paper, so a weak paper can be balanced by a strong one. But the opposite is also true: a handful of careless marks lost in each paper adds up across all five, and that can be the difference between two grades. You can see how the grades work in our guide to B2 First grades.
The good news is that most of the mistakes teachers see again and again are habits, not gaps in your English. Habits can be changed in a few weeks. Below are twelve of the most common ones, grouped by paper.
Reading and Use of English: four mistakes
Trap: 1. Leaving gaps empty. Students skip a hard question to come back to it, then run out of time.
Fix: Never leave a blank. A blank always scores zero; a sensible guess sometimes scores. If you skip a question, write a quick guess first and mark it so you can return.
Trap: 2. Writing more than one word in Parts 2 and 3, or forgetting that contractions count as two words.
Fix: In the open cloze and word formation, write exactly one word per gap. Avoid contractions in Part 4 too, where your answer must be between two and five words including the key word. See the key word transformation guide.
Trap: 3. Changing the key word in Part 4 (for example, turning 'succeed' into 'successful').
Fix: The key word must appear exactly as given. Underline it before you start writing and check it again after.
Trap: 4. Reading every text slowly from start to finish and running out of time for Part 7.
Fix: Set a time budget per part and practise with a timer. Parts 5–7 are long, so do not spend a quarter of the paper on Part 1. Our Reading and Use of English hub suggests a timing plan.
Writing: three mistakes
Trap: 5. Forgetting the third idea in the Part 1 essay, or only using one of the two prompts.
Fix: The essay asks you to use both given notes plus a third idea of your own. Plan three paragraphs for the three ideas before you write a word. Our essay guide shows a plan that works every time.
Trap: 6. Writing the right content in the wrong format: an article that reads like an essay, or a review with no recommendation.
Fix: Each Part 2 task type has a purpose and a reader. Before you write, ask: who is reading this, and what should they do or think afterwards? Check the article, review and report pages for the features each one needs.
Trap: 7. Going far outside 140–190 words, or never counting.
Fix: Practise until you know roughly how many lines of your handwriting make 140–190 words, or check typed drafts with the writing word counter. Too short usually means missing content; too long usually means repetition.
Listening: two mistakes
Trap: 8. Choosing an option because you heard the same word in the recording.
Fix: Words from wrong options are often spoken on purpose. Listen for meaning, not matching words: did the speaker agree, reject, or change their mind? Read our page on FCE listening tips and distractors.
Trap: 9. Misspelling simple words in Part 2 sentence completion.
Fix: Part 2 answers are words you hear, so spelling matters. Keep a list of everyday words you misspell (for example accommodation, environment, necessary) and test yourself weekly. More in the Listening Part 2 guide.
Speaking: three mistakes
Trap: 10. Giving one-word or one-sentence answers in Part 1.
Fix: Answer, then add a reason or an example. Two or three sentences is about right. See the Speaking Part 1 guide.
Trap: 11. Describing the photos in Part 2 instead of comparing them and answering the question.
Fix: The question above the photos is the real task. Compare the two situations and spend most of your minute on the question. The Speaking Part 2 guide has a simple structure for this.
Trap: 12. Ignoring your partner in Part 3 and giving a speech.
Fix: Part 3 is a conversation. Ask your partner's opinion, react to what they say, and build on it. Practise the turn-taking phrases on our speaking phrases page.
The mistake behind all the others: practising without reviewing
Many candidates do practice test after practice test, check the score, and move on. The score tells you where you are. It doesn't tell you why. The marks only start to rise when you look at every wrong answer and name the reason:
- I didn't know the word or phrase. Add it to your vocabulary notebook with an example sentence.
- I knew it, but I misread the question. Slow down at the reading-the-question stage next time.
- I ran out of time. Change your timing plan.
- I fell for a trap. Write down what the trap was, so you recognise it next time.
Keep a simple "error log" with these four columns. After two or three practice sessions you will see a pattern, and that pattern tells you what to study next. Our Use of English common mistakes page lists the grammar and vocabulary errors that appear most often in that paper.
Frequently asked questions
What is the most common mistake in the B2 First?
From a teacher's point of view, the most expensive habit is leaving answers blank. A blank is always zero. After that, ignoring task instructions (word limits, the key word in Part 4, the third idea in the essay) costs a lot of easy marks.
Do spelling mistakes lose marks in the B2 First?
Spelling matters most where you write single words: Use of English Parts 2, 3 and 4, and Listening Part 2. In Writing, occasional spelling slips are part of the overall Language mark rather than a separate penalty, but frequent errors make your text harder to read.
Can I fail one paper and still pass the B2 First?
Your result is the average of the five scores, and there is no minimum score in each paper. So a weak paper can be balanced by stronger ones. The scoring guide explains how it works, and the score calculator lets you test different combinations.
Is it a mistake to use very advanced vocabulary in Writing?
Only if you use it wrongly. A range of vocabulary helps your Language mark, but a rare word in the wrong place makes your meaning unclear. Choose words you are sure about, and show range with good collocations and linking words.
How can I stop making the same mistakes in practice tests?
Keep an error log. For every wrong answer, write the reason and the correct answer. Review the log before each new practice session, and focus your study on the reason that appears most often.
