Before you start speaking:
First look at the instructions.
Try to think of words and expressions you might need.
Use as many expressions as possible; you can use them if you're lost for words. DON'T write out your conversation or talk completely!
If you do that, it will just be a writing and reading exercise!
While speaking:
Make sure you start a conversation by greeting the other person in a polite way. Look at your partner or at your audience.
Speak calmly and not too quietly.
You can use a note, but make sure there are only a few words on it!
If you don't know a word, you can always explain what you can use it for,
or what it looks like.
Try to keep on talking, even if you don't really know how you should say something.
If you don't understand your partner, you can ask for an explanation, or ask your partner to repeat the question.
End a conversation by saying goodbye.
Clue: if you practise a conversation a second time, it will be much easier!
