This is great, I've been looking for a good introductory resource for SQL in a while!

One thing, though, there's a mistake in exercise 3. While it says "Find all the titles directed by John Lasseter", only a "SELECT * FROM movies" query will make it go green, while "SELECT title FROM movies" (as would be expected from the wording) does not.

Is this Open Source?
