This guide provides you with basically all you need to know in order to shine in the Cambridge English C1 Advanced Speaking test. Of course, you need to show the examiners a good range of grammar and strong vocabulary, too. Naturally, that is something you build by reading and studying for the exam.
The e-book consists of the guidelines for each part of the Cambridge English Speaking Paper, lots of useful language which will raise your score for sure. There are full sample answers for each part - you will see the exact way you should speak - and a section where you should practise doing the tasks on your own, with my written prompts and guidance. Also, there's the assessment guide.
Finally, at the end of the book you can find a bonus section with strategies, tips, powerful speaking techniques, and a vocabulary bank section. (You can use this bonus section in your writing tasks, too.)
