Using ChatGPT to Practice TOEIC Grammar

Using ChatGPT to Practice TOEIC Grammar

Master Key Rules and Eliminate Mistakes with AI-Powered Practice

Introduction

Grammar is one of the most feared parts of the TOEIC test—but it doesn’t have to be. Whether it’s subject-verb agreement, tricky verb tenses, conditionals, or prepositions, TOEIC grammar questions are designed to test your accuracy under pressure. For many learners, this means frustration, repeated mistakes, and endless review.

But what if you could ask for a clear explanation—any time, anywhere? What if you had a personal grammar tutor available 24/7 who could give you custom practice and instant feedback?

That’s exactly what ChatGPT offers.

In this article, we’ll explore how to use ChatGPT to identify your grammar weaknesses, drill key TOEIC question types, and master difficult rules through smart prompts. Whether you’re aiming for a high score or simply want to feel more confident with English grammar, ChatGPT can help you study more efficiently and effectively.

Let’s take a closer look at why TOEIC grammar is so challenging—and how AI can help you finally get it right.

Section 1: Why Grammar Matters in the TOEIC Test

Many English learners believe that vocabulary is the key to TOEIC success—and while that’s partly true, grammar plays an equally important role, especially in the Reading section. Without solid grammar skills, even a strong vocabulary won’t help you avoid common traps.

Here’s why grammar matters more than you might think:

✅ Part 5: Incomplete Sentences

This section is grammar-heavy by design. You’ll encounter questions that test:

• Subject–verb agreement

• Verb tense and aspect

• Conditional forms

• Comparatives and superlatives

• Articles, prepositions, and conjunctions

Example:
“The team members _____ the results before the meeting.”
(A) discusses (B) discussed (C) discussing (D) has discussed

A strong understanding of subject-verb agreement and past tense rules is essential to get this right.

✅ Part 6: Text Completion

While Part 6 also includes vocabulary, many of its questions require you to understand grammar in context—how a verb or article fits into a full paragraph.

• You must be able to choose the grammatically correct option based on surrounding sentences.

• Transitions and modifiers are especially important here.

✅ Part 7: Reading Comprehension

Grammar helps you read more efficiently. If you can quickly recognize sentence structure, identify main clauses, or understand passive voice, you’ll read faster and understand more.

• Misreading one grammar structure can lead to confusion in meaning and wrong answers.

Grammar = Precision

TOEIC rewards clarity and precision. Knowing the difference between “has been,” “had been,” and “was being” may seem minor—but it can mean the difference between a correct or incorrect answer.

Bottom Line

Grammar is not just about memorizing rules. It’s about understanding how English works, especially in business and formal contexts. If you want to boost your TOEIC score, focusing on grammar is a high-return investment.

In the next section, we’ll look at the most common grammar challenges TOEIC learners face—and why they’re so tricky to master.

1. Verb Tense Confusion

TOEIC tests your ability to distinguish between past, present, and perfect tenses—with subtle variations.

Example:
“The report ___ submitted before the meeting started.”
(A) is (B) was (C) has been (D) had been

Many learners confuse “has been” and “had been,” especially when time clauses are involved.

✅ 2. Subject-Verb Agreement

Singular/plural mismatches are one of the most common errors, especially with complex sentence structures.

Example:
“Each of the applicants ___ required to bring their ID.”

Answer: “is” (not “are”)—“Each” is singular.

3. Passive vs. Active Voice

TOEIC uses both active and passive structures, often in professional or formal business contexts.

• “The manager approved the request.” (active)

• “The request was approved by the manager.” (passive)

Many learners misidentify the subject, leading to errors in tense and form.

❓ 4. Articles and Countability

A/an/the usage is deceptively tricky, especially for non-native speakers whose languages don’t use articles.

“Please complete the form and return it to ___ HR department.”

Correct answer: “the HR department”

5. Conjunctions and Sentence Structure

TOEIC frequently tests whether you can link ideas properly using conjunctions like “although,” “while,” “because,” and “however.” These connect grammar and logic.

• “Although the price was high, the customer placed an order.”

• “However, the item was no longer in stock.”

6. Prepositions in Business Contexts

Words like “by,” “with,” “under,” “within,” and “among” are often used in very specific professional contexts.

“The report must be submitted ___ Friday.”

Answer: “by Friday”

These tiny words often cause big problems on the test.

Why Are These So Hard?

• Rules are often exceptions-based.

• Many students learn grammar in isolation, not in real usage.

• Textbooks rarely reflect the nuance of TOEIC’s formal/business context.

• Time pressure during the test leads to panic-based guessing.

In the next section, we’ll explore how ChatGPT can help fix these exact problems—with real-time explanations, examples, and custom practice.

Section 6: Case Study — A Student’s 4-Week Grammar Breakthrough with ChatGPT

Meet Luis, a 29-year-old engineer from Mexico preparing to work in an international company. To qualify for a promotion, he needed to improve his TOEIC score from 620 to at least 750—and his biggest weakness was grammar.

Luis enrolled in a 4-week TOEIC bootcamp at 3D ACADEMY in Cebu, where he attended daily one-on-one classes. But outside the classroom, he took his learning to the next level using ChatGPT as his personal grammar coach.

Here’s how Luis used ChatGPT—and how it changed his results.
