Getting wrong answer

Like before, select the average "score" as "average", setting to 0 if null, by grouping the "movie_id" from the "reviews" table. Also, do an outer join on the "movies" table with its "id" column and display the movie "title" before the "average". Finally, include averages under 2.

Hey Anuj,

Could you post the code that you're using, so we could take a look?

Hey David, I am using this code :-

SELECT title, IFNULL(AVG(score),0) as average FROM movies LEFT OUTER JOIN reviews ON movies.id = reviews.movie_id GROUP BY movie_id HAVING average < 2

Hi Anuj,

You may want to try refreshing the challenge and trying again.

Your query looks correct to me and it passed the challenge when I copied and pasted it in.
