Welcome to this comprehensive practice session designed to sharpen your linguistic precision. In the TOEIC® exam, the difference between a high score and a perfect 990 often lies in the details: choosing the right suffix, identifying the correct tense for a timeframe, or spotting the subtle cues of a superlative comparison.

This interactive quiz features 30 original questions modeled after Part 5 of the actual exam. You can practice using the Timed Mode with 20 seconds allocated for each question or take your time in Relaxed Mode. Use this as a diagnostic tool to identify your strengths and bridge any gaps in your grammar knowledge. Let’s get started!
TOEIC® Mastery Challenge
30 Questions: Verb Forms, Word Families, & Comparisons
Quiz Complete!
1. Word Families (Parts of Speech)
Identifying the correct suffix is the fastest way to solve Part 5 questions.
- Nouns (-tion, -ment, -ity, -ance): Look for these after "the," "a/an," or possessive adjectives (my, your, company’s).
- Adjectives (-able, -ive, -ous, -ent): Use these to describe nouns or after "linking verbs" like *be, become, feel, seem*.
- Adverbs (-ly): Use these to modify verbs, adjectives, or entire sentences.
2. Verb Forms: Gerunds vs. Infinitives
The TOEIC® tests your knowledge of what follows a preposition or specific verb.
- Always use a Gerund (-ing): After prepositions (in, at, by, with, after, before) and verbs like mind, avoid, suggest, and finish.
- Always use an Infinitive (to + verb): After verbs like decide, plan, hope, and attempt.
- Imperatives: For instructions or requests (starting with Please), use the Base Form (e.g., Please submit).
3. Comparison Mastery
Watch for the "keywords" that signal which degree of comparison to use.
| Type | Keyword | Structure |
|---|---|---|
| Comparative | than | -er / more + adj |
| Superlative | the / of all | -est / most + adj |
| Equality | as...as | as + adj + as |
