Ielts speaking--how to improve your bandscore

How and when do we make notes?
One-minute preparation time is allocated before you start speaking in IELTS
Speaking part 2. This is the period when you have to use the sheet of paper given
by the examiner where you can write down keywords and ideas on.
As mentioned in lesson 3, you have to write the keywords of your answer, which
may be a noun, verb, pronoun, or adjective. Write at least 3 less common words
for you to have a better score in lexical resource.
Write notes for every question on the cue card. Never skip one, for your failure
to answer one of the questions from the topic card would mean a penalty on your
score.
