Doing Many TOEIC Practice Tests, But Scores Aren't Increasing: What Are You Missing?

There's a very common way to study for TOEIC: do practice tests, check answers, write down new words, then do more practice tests. Scores might increase a little at first, but then they plateau. The more you do, the more familiar the questions seem, but when you encounter new tests, you still make the same old mistakes.

The reason: doing practice tests only tells you what you got wrong. It doesn't automatically fix what caused you to make those mistakes.

Doing Many Practice Tests Doesn't Mean You're Getting Better

A TOEIC practice test can show you where you stand. But if today you can't make out a sentence when listening, then just check the answer and move on, chances are you still won't catch a similar phrase next time.

For example, you chose the wrong answer because you couldn't hear a certain phrase. After looking at the transcript, you realize: “Oh, I know this word.”

The problem isn't that you don't know the word. The problem is that you only recognize it when reading, but you haven't learned to recognize it when a native speaker says it at a natural speed.

If you don't address this gap, doing 10 more practice tests will only mean you're repeating the same error across 10 different tests.

TOEIC Doesn't Just Test Vocabulary and Grammar

Many people think studying for TOEIC means learning a lot of vocabulary and remembering many tricks. But in the Listening section, the sentences you hear are often not like the sentences you've studied on paper.

Speakers link sounds, reduce sounds, and emphasize important words. A very simple sentence can become difficult to understand when spoken at a natural speed.

The Reading section has a similar issue. Correct answers rarely repeat the exact information from the text verbatim. The test often expresses the same idea in a different way.

Therefore, TOEIC doesn't just ask: “Do you know this word?”

It also asks: “Do you recognize this word when you hear it?” and “Do you recognize the same idea when it's expressed in a different way?”

To Increase Your Score, You Must Know Exactly Where You're Making Mistakes

After each incorrect answer, don't just look at the right answer. Find the cause.

Don't you know the word? Do you know the word but can't hear it? Can you hear individual words but not understand the whole sentence? Or do you understand the question but not recognize the paraphrase in the answer choices?

Each type of mistake requires a different practice method.

If you don't know the word, you need to learn words in context. If you know the word but can't hear it, you need to listen again and do dictation. If you can hear but react slowly, you need to practice more at a natural speed.

That's why simply doing practice tests continuously is often not enough.

How to Practice to Truly Increase Your TOEIC Score

Dictation helps you pinpoint exactly which parts your ears are missing. When you have to type every single word, connected sounds, end sounds, and reduced words no longer slip by easily.

Shadowing helps you get accustomed to natural speech speed and rhythm. When your mouth gets used to how a phrase is pronounced, your ears will recognize that phrase faster too.

And doing practice tests helps you check if what you've practiced has truly translated into a score.

These three activities have different roles: doing tests to identify mistakes, deep practice to correct mistakes, then returning to tests to check progress.

This is also how Parroto approaches TOEIC: not just doing many questions, but helping you identify your weaknesses and practice those specific skills through dictation, shadowing, and real-world content — so that each subsequent test isn't just another test completed, but genuine improvement over the last time.
