TOEIC Part 5: the grammar part, and how to clear it fast

Part 5 is 30 short grammar-and-vocabulary questions — the fastest, most bankable points on the whole TOEIC. Here's its exact format, the five patterns ETS tests, real sample questions with answers, and a 20-second method that protects your clock for Part 7.

ABCD 101
⚡ The short answer

TOEIC Part 5 (Incomplete Sentences) is 30 questions — numbers 101 to 130 — each a single sentence with one blank and four choices (A–D). It opens the Reading section and it's the fastest part on the test: aim for about 20 seconds a question, roughly 10–12 minutes total.

The trick is to look at the four options first. Four forms of one word means it's a grammar question — decide the part of speech. Four different words means it's vocabulary — read for meaning. That one habit is most of the battle.

What TOEIC Part 5 actually is

Part 5 is the first part of the TOEIC Reading section. According to the official ETS Examinee Handbook, it contains 30 questions, numbered 101 to 130. The directions are simple: "A word or phrase is missing in each of the sentences below. Four answer choices are given below each sentence. Select the best answer to complete the sentence."

Every question is one self-contained sentence — no passage, no context beyond the sentence itself. That's what makes Part 5 both fast and unforgiving: there's nowhere to hide, but also nothing extra to read.

Why Part 5 is your points bank

The Reading section gives you 75 minutes for 100 questions, and there's no separate timing between parts. That means Part 5 has a double value: it's worth 30 questions and it's where you buy time for Part 7, the long-passage monster at the end. Every minute you overspend on a single-sentence grammar item is a minute stolen from a 5-question reading set later.

Part 5 feeds the Reading section score, which the Handbook confirms runs from 5 to 495 (it sums with Listening to the familiar 10–990 total). Because the test is statistically equated, you can't put a point value on one question — but 30 fast, high-accuracy answers is one of the cleanest ways to lift a Reading score, especially compared with the slow grind of Part 7.

⏱️ The 20-second rule

If a Part 5 question takes you more than ~30 seconds, mark your best guess, flag it, and move. There's no penalty for a wrong answer, and the time is worth far more to a Part 7 set than to one stubborn sentence.

The 5 patterns ETS tests — with real examples

Part 5 looks varied, but almost every question is one of five recognisable types. The examples below are the real opening questions (101–105) from ETS's official sample test — a perfect cross-section, because they happen to show four of the five patterns in a row.

1. Word form (part of speech)

The four options are the same word in different forms. Your job is to decide what part of speech the blank needs — noun, verb, adjective or adverb — from the words around it.

Real example — Question 101

"Customer reviews indicate that many modern mobile devices are often unnecessarily ______."

  • (A) complication   (B) complicates   (C) complicate   (D) complicated ✓

Why (D): after the linking verb "are" and the adverb "unnecessarily," the blank needs an adjective to describe the devices. "Complicated" is the adjective form. You never had to understand the sentence deeply — just the grammar around the gap.

2. Connecting words (prepositions & conjunctions)

The options are linking words — since, although, because, during, despite — and the answer depends on the logical relationship between two parts of the sentence.

Real example — Question 102

"Jamal Nawzad has received top performance reviews ______ he joined the sales department two years ago."

  • (C) since ✓ — links the reviews to a starting point in time ("since he joined").

The clue: "two years ago" plus the present-perfect "has received" signals a time span from a starting point — the job of since.

3. Verbs (tense, voice & agreement)

The options are forms of a verb, and you choose based on tense, subject–verb agreement, or active vs. passive voice. Look for time markers (already, next week, since) and whether the subject is singular or plural.

4. Pronouns & determiners

The options are pronouns or determiners — it / them / those / their — and you pick the one that agrees with the noun it stands for.

Real example — Question 104

The answer is (D) those — a determiner pointing to a specific plural group. Pronoun questions are pure grammar: match number (singular/plural) and role, and you don't need the sentence's meaning at all.

5. Vocabulary & collocation

Here the four options are different words of the same part of speech, and only one fits the meaning — often because of a collocation (words that naturally go together, like "make a decision" or "meet a deadline"). These are the questions where you must read for meaning.

Real example — Question 105

The answer is (B) synthetic. All four options are adjectives that fit grammatically — only the meaning tells them apart. This is the tell of a vocabulary question: when the grammar can't decide it, the meaning must.

🔑 Grammar or vocabulary? Read the options first

Four forms of one word (complicate / complicates / complicating / complicated) → a grammar question; solve it by part of speech, fast. Four different words (synthetic / durable / gradual / hollow) → a vocabulary question; read the sentence for meaning. Deciding which before you read closely is what buys you speed.

The 20-second method

Speed in Part 5 comes from a fixed routine, not from reading faster. Run every question through the same four steps:

  1. Glance at the four options. Same word in different forms, or four different words? This tells you instantly whether you're solving grammar or meaning.
  2. If it's grammar, find what the blank needs. Look at the words touching the gap: an adverb before it and a linking verb usually wants an adjective; "the ______ of" usually wants a noun; a subject with no verb wants a verb. Decide the part of speech, then pick the option that matches.
  3. If it's vocabulary, read the whole sentence once. Meaning is the only judge, so read the full sentence and test each word — a collocation or a context clue usually settles it.
  4. Eliminate and commit. Rule out what's grammatically impossible, choose the best of the rest, and move. If you're still stuck past ~30 seconds, guess, flag, and go.

The Part 5 pacing target (75-minute Reading section)

  • Part 5 (101–130): done by the 12-minute mark — ~20 seconds each
  • Part 6 (131–146): done by the 20-minute mark
  • That leaves ~55 minutes for Part 7's 54 questions
  • Golden rule: never let one sentence cost you a reading set

The traps that cost easy points

  • The "sounds right" word form. ETS loves offering a noun where an adjective belongs. Don't trust your ear — check the grammar of the words next to the blank.
  • Near-synonyms in vocabulary questions. Two options often mean almost the same thing; the answer is the one that collocates with the surrounding words. Learn common collocations, not just word lists.
  • Ignoring time markers. On verb questions, a single word — already, since, next, yesterday — usually fixes the tense. Missing it turns a 10-second question into a guess.
  • Over-reading. On grammar questions you rarely need the sentence's meaning. Reading every clause "to be safe" is how a 20-second question becomes a minute.

How to practise Part 5 so it sticks

Part 5 rewards pattern recognition, and pattern recognition is built by volume plus review. Two habits move the needle fastest:

  • Sort every miss into one of the five patterns. Were you wrong on a word form, a connecting word, a verb, a pronoun, or a vocabulary choice? A stack of "word form" misses tells you exactly what grammar to review — far more useful than a raw score.
  • Practise under a clock. Untimed grammar drills teach accuracy but not the 20-second reflex Part 5 actually rewards. Do timed sets, then full Reading sections, so the pace becomes automatic.

That's how our free mocks are built: full-length Reading sections in the official 2026 format, auto-scored on the 5–495 scale, with the AI coach tagging which Part 5 pattern each miss belongs to — then turning your weakest pattern into targeted drills. And once your grammar is quick, read our Part 7 guide to spend the time you've banked where it counts.

Frequently asked questions

How many questions are in TOEIC Part 5?
Part 5 (Incomplete Sentences) has 30 questions, numbered 101 to 130. Each is one sentence with a single blank and four choices (A–D).
How long should I spend on Part 5?
About 10–12 minutes for all 30 questions — roughly 20 seconds each. It's the fastest part of the 75-minute Reading section, and the time you save funds Part 7.
Is Part 5 grammar or vocabulary?
Both — roughly half and half. Grammar questions (word form, verb, connecting word, pronoun) can often be solved from the words around the blank; vocabulary questions need you to understand the meaning of the sentence.
What's the fastest way to answer Part 5?
Look at the options first. Four forms of one word = a grammar question (decide the part of speech). Four different words = a vocabulary question (read for meaning). That split tells you how to solve it before you read closely.
Is there a penalty for guessing on Part 5?
No. The TOEIC never deducts points for wrong answers, so never leave a blank. Eliminate what you can and guess — a guess can only help your score.
