IELTS Speaking Part 2: start with vocabulary ideas

 The model answer that I shared last Friday was at band 9 level, mainly because of the range of words and phrases that it contained.

But I didn't spontaneously invent those words and phrases; they came from my research into the topic. I searched for good ideas, made a list of topic vocabulary, and then built my description around the phrases on that list.

I'm not suggesting that you can do this in your test, but it's the best way to prepare topics at home.
