To master the IELTS at a C1 or C2 level (Band 7.0–9.0), you must move beyond basic synonyms. You need "less common lexical items" used with precision, correct collocation, and natural style.

Transcribing:

Listen to a passage and write it down to see how advanced words are spelled and used in sentences.

1. Play Track: Listen to one sentence from the Cambridge Audio.
2. Pause: Repeat the sentence exactly.
3. Rewrite: Without looking, write down the sentence.
4. Compare: Check your spelling and word order against the transcript.

Conclusion

Engagement

: A few readers described the material as "boring" or dry.
