Here is a task you should do in order to prepare for the exam. The idea is to make a sentence from five words. The examples are rather difficult and not very intuitive. I can say with confidence that your exam task will be a bit easier, but have a try.
See also Taking a message for a listening exercise. Both of these tasks will be part of your exam.
Merry Christmas and a happy new year! See you in 2016.
