Here’s the latest version of the Cambridge IELTS Test book series (Cambridge 13).
I’ll be posting the sample responses (script) for the questions above any time soon.
Meanwhile, try answering these questions on your own. It’ll be helpful if you also record your answers in the process. That way, you can assess yourself on what you need to work on in the future (Pronunciation, Fluency and Coherence, Lexical resource, and Grammar range and accuracy).
Good luck practicing for the Band score you need!
