Why Vocabulary Matters for IELTS?

Lexical Resource = 25 % of Your Writing & Speaking Score

The IELTS rubric awards a full quarter of the marks in Writing and Speaking to "Lexical Resource.” A broader, more accurate vocabulary lets you choose the perfect word, avoid repetition, and demonstrate a native-like command of collocations—exactly what examiners are trained to reward.

Faster Comprehension in Reading & Listening

Knowing the key words that appear in passages and recordings reduces the time you spend decoding meaning. That extra time can be reinvested in locating details, verifying answers, and avoiding traps, directly translating into higher raw scores.

Precision & Variety Boost Task Achievement

Rich vocabulary lets you express complex ideas clearly and concisely, linking arguments with precise connectors. This not only raises coherence but also shows examiners you can handle a range of topics, pushing your band score toward 7 +.
