Grader doesn't work properly for C3W3 Assignment

HI team!

I am currently working on the C3W3 SQL assignment, and I believe my query and output match the expected result. However, the grader keeps failing the test case for exercises 4, 11, 12, indicating that my output is incorrect, even though it looks correct on my end.

Steps I’ve taken so far:

  1. Verified that the output matches the expected format exactly, including the column names and values.
  2. Cleared cell outputs, restarted the kernel, and re-ran the necessary cells to ensure fresh data is produced.

Despite these efforts, the grader keeps showing that the output does not match. Could there be a bug with the grader or an issue with the specific notebook I am using?

Please advise on how I can proceed or if there are any known issues with this assignment’s grading.


Hello @TetianaKravchenko your output is correct, however it seems you are missing the correct tag from the cell:

You could try adding it, right click on cell>notebook cell>add cell tag
and type ex11,ex12 etc.

Then submit again, should look like this:
