Hello everyone!
My post refers to Code Challenge: Working with Multiple Tables that I’m doing as a part of the Data Science path. Here’s the link to the lesson in question:
On the first page there’s an introduction to the tabels user is going to work with. I believe there’s a mistake in “plays” table, row “song_id”. It has a copy-pasted text from “premium_users” table, row “membership_plan_id” but I think it should be described differently.
It’s a minor typo, I know, but thought I could inform you of it so the course could get cleaner 
Cheers!
