Ielts speaking--how to improve your bandscore

Chapter Nine:
Synonyms and related expressions
What is the importance of synonyms and related expressions in getting your
desired band score in the Speaking test?
Vocabulary range and accuracy is one of the criteria in the assessment of your
speaking. The knowledge and use of synonyms are crucial to achieve a high
band score because these help you avoid repeating words and help you express
your thoughts with precision, which are closely observed by the examiner.
To achieve band 7, a candidate must use the vocabulary resource flexibly to
discuss a variety of topics. Using words flexibly means that a candidate should
not use the same words when discussing a variety of topics. Repetitive answers
are penalized, and candidates who do so are likely to get a lower band.
