When to do Language and Culture lessons?

I'm sure I'm just missing it, but what is the recommended approach to doing Language & Culture lessons. There does not appear to be a one-to-one correspondence of those lessons to the interactive audio lessons. Thanks, Jean

Ciao Jean, the language and culture lessons are created to familiarize yourself as well as discover Italian customs. There is no connection to the interactive audio lessons therefore you can go through them at the end of each audio lesson or at the end of each section. I hope you enjoy them :) Ciao
