Hi Pat, welcome to the Forum. Hope you enjoyed the first six lessons!
I THINK I’m right in saying that these practices are refreshed on a weekly basis (Sundays, I think), so you will always be covering slightly different ground to before.
The idea is to download a particular day’s practices, and after you’ve listened to/spoken them, delete them and download the next day’s, and so on.
Pob lwc!. These practices are useful, and although the speaking ones can sometimes be a bit challenging at times, they are also enjoyable.
