Hi Olaf,
You can do these dialogues:
Then we can record them on the 22nd of May. You can practice a lot too by listening to the audio trainer every day for 10 minutes on your phone to practise everything we learned so far. Listen to the dialogue recordings too regularly.
If you have time, you can also read P20 – A/B and then exercises 5.1/5.2 on page 21.
All the very best for the time off.
Paul.
