Does anyone know where this Egyptian Arabic lesson is from?

Thing is I think it was posted on a webpage (i think it was free to share) and it had many other languages available. And now I’m trying to find that resource cause I think it had great Russian content that could be imported into Lingq. For public or maybe private lessons.

I remember that Russian had pdf + audio of someone buying a flat. And one lesson was a person being at the dentist’s office.

Any ideas. I’ve tried to search my browsing history but no success for now. So it would be great if someone remembers where this could be from.

I already msged the original poster but they are not active anymore so I didn’t get any answer.
