#15 Test Day Mistakes That Cost You Marks
You have studied for weeks or months. You know the strategies. But on test day, small mistakes — most of them completely avoidable — can cost you 0.5 to 1.0 band scores. Here are 15 mistakes I have seen candidates make repeatedly, with specific advice on how to avoid each one.
#1. Arriving Late or Flustered
Test centres close registration 15–30 minutes before the exam. If you arrive at the last minute, you start the test with elevated stress hormones, which impair cognitive function. Solution: Arrive 45 minutes early. Bring water, your ID, and nothing else to worry about.
#2. Not Reading Instructions Carefully
"Write NO MORE THAN TWO WORDS" — if you write three words, the answer is marked wrong even if the content is correct. Every section has specific instructions. Solution: Read the instruction line before every set of questions, even if you think you know the format.
#3. Poor Time Management in Reading
Spending 25 minutes on Passage 1 (the easiest) leaves only 35 minutes for Passages 2 and 3 combined. Solution: Set strict time limits — 15/20/25 minutes — and move on when time is up, even if you have not finished.
#4. Writing Answers in ALL CAPITALS
While the official guidance says capitals are acceptable in Listening and Reading, using all caps in Writing makes your handwriting harder to read and can affect the examiner's impression. More critically, if your capital letters are ambiguous (is that a C or an O?), the examiner may mark it wrong. Solution: Write in clear lowercase with capitals only where grammatically appropriate.
#5. Not Transferring Answers in Listening
You get 10 minutes at the end of the Listening test to transfer answers to your answer sheet. Some candidates write answers on the question paper during the test and then forget to transfer them — or run out of time. With computer-based IELTS, this is less of an issue as you type directly, but for paper-based tests: Solution: Transfer answers immediately after each section if possible, using the checking time.
#6. Leaving Blank Answers in Reading
There is NO negative marking. A blank answer scores zero. A random guess has a chance of being correct. Solution: In the last 2 minutes, fill every blank answer with your best guess. For True/False/Not Given, cycle through the options. For multiple choice, pick something.
#7. Not Planning Your Essay
Candidates who dive straight into writing often produce disorganised essays that wander between ideas. Solution: Spend 5 minutes planning Task 2. Write down your position, two or three main ideas, and one supporting point for each. This investment pays for itself in coherence marks.
#8. Ignoring the Word Count in Writing
Writing fewer than 150 words in Task 1 or fewer than 250 words in Task 2 results in a penalty. Writing significantly over the count (400+ words for Task 2) means more errors and less time for checking. Solution: Know how many words your handwriting produces per line, and count roughly as you write.
#9. Speaking Too Quietly
The Speaking test is recorded. If the examiner — or the recording — cannot hear you clearly, your pronunciation score suffers. Solution: Speak at a normal conversational volume. Project your voice slightly more than you would in casual conversation. If in doubt, ask the examiner "Can you hear me clearly?"
#10. Not Asking the Examiner to Repeat
In the Speaking test, you are allowed to ask "Could you repeat the question?" without penalty. Answering a question you misheard is far worse. Solution: If you did not catch the question, ask for repetition. It is natural and examiners expect it. You can also ask in Part 3: "Do you mean…?"
#11. Memorising and Reciting Answers in Speaking
Examiners are trained to detect rehearsed answers. If your Part 2 response sounds unnatural or pre-scripted, the examiner will note it and your score will drop. Solution: Practise speaking about topics, but never memorise word-for-word responses. Prepare ideas, not scripts.
#12. Changing Answers Without Good Reason in Listening
Research shows that first instincts in listening are usually correct. Candidates who change answers during the transfer time often change correct answers to wrong ones. Solution: Only change an answer if you are genuinely certain your first response was wrong — not because you are second-guessing yourself.
#13. Writing the Wrong Task First in Writing
Task 2 is worth twice as many marks as Task 1. If you spend too long on Task 1 and rush Task 2, you lose marks where they matter most. Solution: Start with Task 2 (spend 40 minutes), then do Task 1 (spend 20 minutes). Alternatively, if you start with Task 1, set a strict 20-minute alarm and stop.
#14. Panicking on a Difficult Listening Section
If you miss an answer in Listening, many candidates mentally freeze — they are still thinking about question 15 when question 17 is being read. Solution: If you miss an answer, immediately move to the next question. Write a dash and move on. You cannot go back in time, but you can save future answers.
#15. Not Checking Spelling in Listening and Reading
"Accomodation" instead of "accommodation." "Goverment" instead of "government." Spelling errors cost full marks in Listening and Reading gap-fill questions. Solution: Use your transfer time to double-check spelling of common words. Practise the 100 most commonly misspelled IELTS words before test day.
#The Night Before
Avoid studying the night before the test. Your brain needs rest to perform optimally. Lay out your ID, pencils, and eraser. Set two alarms. Get 7–8 hours of sleep. A rested brain performing at 90% will always outscore an exhausted brain performing at 60%.
