C3_W1 Assignment grading

[thazed]

I just completed the assignment and it indicated I missed 4 or the 5 points in Exercise 1. I opened to see the details and found:

I see the same feedback on exercise 4:

Help me understand the difference between count(*) (expected) count(n) (my answer) which return the exact same results.

Thanks.

Hello @thazed,

The grader is sensitive to the output and it gives less points. You could change the queries on those Exercises from count(n) to count(*), there would be a difference if there were more n values than total. Hope it helps
