The mistakes that cost most on the TOEIC
None of them are English mistakes. All of them can be fixed in a single session.
The mistakes that cost most on the TOEIC are almost never mistakes in English. They are mistakes in method, they repeat from one candidate to the next, and they can be fixed in a single session — which makes them the cheapest points on the paper.
The number one mistake, by a wide margin
Leaving answers blank. There is no penalty for a wrong answer: your raw score is the number of correct ones, full stop. A blank and a wrong answer are worth exactly the same. Fifteen unattempted questions at the end of Part 7, filled in at random, return three or four correct on average. Left blank they return nothing.
Listening mistakes
Practising with the transcript in front of you
This is the most common and most expensive training mistake. Reading the text while you listen removes precisely the difficulty being measured: on test day nothing is printed in Part 2, and only the questions are printed in Parts 3 and 4. A candidate trained with the text meets the real task for the first time in the exam room.
Staying on a question you missed
The tape keeps going. Time spent regretting an answer is time stolen from the next two questions in the same block. A lost question costs one point; clinging to it costs three.
Choosing the reply that repeats a word you heard
In Part 2 especially, a reply that repeats a word from the question is almost always a trap. The test works by rewording: the correct answer says the same thing in different words. That holds across all four listening parts.
Reading mistakes
Treating Part 5 carefully
It sounds backwards, and it is still the most widespread pacing error. Thirty questions at a minute each is thirty minutes taken from Part 7, where they were worth about thirty more questions reached. Part 5 should be dispatched, not polished.
Reading the whole passage before the questions in Part 7
Reading the document and then hunting for answers means reading it twice on a clock that allows once. Questions first, scan second.
Treating Part 6 like Part 5
Part 6 looks like a gap-fill and works at paragraph level: since 2016, one blank per passage asks you to insert a complete sentence, and several others depend on a tense used three lines further down. Answering sentence by sentence is guessing on those items.
Preparation mistakes
| Common mistake | Why it costs | Do this instead |
|---|---|---|
| Sitting mock test after mock test without reviewing | You rehearse your errors instead of fixing them | Half your time on reviewing mistakes |
| Revising lists of rare words | The test uses ordinary vocabulary, precisely | Work on synonyms and collocations |
| Practising on the old format | Error recognition was removed in 2016 | Check that Part 6 is a text-completion task |
| Never sitting two hours straight | Second-hour fatigue is never tested | One full mock test a fortnight |
| Retaking with nothing changed | Under 35 points, the gap is statistical noise | Work first, book second |
Training on a retired format
The TOEIC changed in 2016: error recognition disappeared and Part 6 became a text-completion task. Many free resources still publish the old format. The check is instant: if you are asked to spot a faulty underlined segment in a sentence, you are working on a test that no longer exists.
Test-day mistakes
- An expired ID. It closes the door, with no appeal and no refund.
- Arriving exactly on time. Nobody is admitted after materials are distributed.
- Counting on a break. There is none between the two sections.
Watch yourself make them
One timed part is enough to expose all of them. Sit a Part 5 with eleven minutes on the clock: the timer will tell you whether your problem is language or method.
For what each part expects, the TOEIC part by part sets it out. And if you are thinking of retaking, how many times you can sit the TOEIC gives the threshold at which it makes sense.

Finishing the TOEIC reading section
Not finishing is not a language problem. It is an allocation problem, and it has a fix.
Improving your TOEIC listening score
One hearing, no pause, nothing printed in Part 2. Train for that, not for a quiz you can replay.
How many times can you take the TOEIC?
Unlimited attempts, no visible history. What decides the retake is the score gap, not the rules.
