Level 1 week 3

Hello, It mentions at the end of this session to use audio files etc to practice during the week. I’ve done the session twice and want to do a bit more if possible - Where would I find these audio files?
I have the App on my phone and this seems to have lots of challenges etc on it - is that what is being referred to?

Yes, if you’re using the app then you have the audio files. The suggestion is for people doing the sessions on a computer. They can download the audio files as mp3s and it’s easier to practise like that.

That’s great Thank you.
Is it the listening exercises at the bottom that say
15-19 etc.
Do they correspond to any lessons or do you just work through them?
Apologies for all the questions.
