Ielts speaking--how to improve your bandscore

Understanding Band Scores
Each of the three tasks is rated against four criteria: fluency and coherence,
lexical resource, grammatical range and accuracy, and pronunciation.
Scores range from 0–9; a 0.5 band is also possible, which makes a big difference
(contrary to how it looks).
In improving band scores, constant testing, which Cambridge tests provide, will
not be sufficient. After establishing your IELTS level, you then need to progress
to building up the skills necessary and addressing identified weaknesses.
Realistically, this can only be achieved through continuous immersion in
English.
The following table provides a high level description of the English language
competences associated with each band score level. These are called the General
Descriptors for IELTS Speaking.
