I think your second code challenge question is broken, the avg's I see are all below 0.

I wish I could add screen shots, I have them saved, but here is the code I ran. SELECT AVG(score) AS average FROM reviews GROUP BY movie_id HAVING average > 2;

Hey,

The query above must be failing I suppose. Maybe that's why you're having a weird result.

I guess you are talking about question 2, here is what you should type :

SELECT AVG(score) AS average FROM reviews GROUP BY movie_id HAVING average < 2;

The code challenge asks to filter out any average value above 2, hence you should keep only the ones below 2.

Hope this helps,

Cheers,
