I’m preparing for the IELTS Speaking test and my biggest worry is freezing up if I get a topic I haven’t prepared for. I can handle familiar subjects, but I need strategies to think on my feet and keep talking coherently. I read an article on jogo do tigrinho about improvisation and structuring spontaneous responses, which offered some useful concepts. Does anyone have practical methods or phrases to buy time and organize thoughts when surprised by a question? How do you practice for the unpredictable?
