Learning vocabulary is very important for the TOEIC exam because:

Reading Comprehension – Many questions require understanding words in context, including synonyms and idioms. A strong vocabulary helps in grasping the meaning of passages quickly.

Listening Comprehension – TOEIC Listening includes conversations and talks with workplace-related vocabulary. Knowing common business terms improves understanding.

Answering Speed – Limited vocabulary can slow down reading and listening, making it harder to finish on time.

Grammar & Meaning – Some questions test word choice, collocations, and phrasal verbs. Expanding your vocabulary prevents confusion in these areas.
