How important is Lexical Resource in IELTS?

I am preparing for IELTS this year, I want to know the importance of Lexical Resource in the exam? Any suggestion would help, thanks!

Lexical resource is a vital part of your IELTS score, making up a full 25% of your overall result. For anyone aiming for a Band 7 or higher, it’s absolutely crucial to understand and demonstrate strong lexical resource. This means showing the examiners you have a wide range of vocabulary and can use it accurately and appropriately.

Think of it this way: you’re being assessed equally on fluency, vocabulary, grammar, and pronunciation. If you neglect your vocabulary, you’re essentially losing a quarter of your potential score. Therefore, mastering the use of diverse and precise vocabulary is not just helpful, it’s essential for achieving your desired IELTS band.
