Why Vocabulary Is Essential for the TOEIC®

Vocabulary is one of the pillars of TOEIC® success. Whether in the Listening or Reading section, every question relies on your ability to understand words and expressions used in a professional context. A solid vocabulary lets you understand questions faster, eliminate wrong answers, and save precious time.

The TOEIC® does not test specialized technical vocabulary, but rather everyday English used in the workplace: meetings, emails, negotiations, business travel, human resources, etc.
