Why Vocabulary Matters in IELTS

In the IELTS test, vocabulary is assessed under Lexical Resource.

Examiners look for your ability to:

• Use a wide range of vocabulary.
• Choose words accurately.
• Avoid repetition.
• Use collocations naturally.
• Spell words correctly.

Remember, using simple words correctly is always better than using difficult words incorrectly.
