General error in the lab

Im solving course 3 week 3, although my code is correct since I passed all test and everything was accepted, my grade is still 0% . Please advi

You filed this under General Discussion, so we have no idea which Specialization you are talking about. There are lots of them that have at least 3 courses. You can move this to the appropriate category by using the little “edit pencil” on the title.

The one general thing we can say is that in all specializations, just passing the tests in the notebook does not guarantee passing the grader. There may be some way in which your code is not “general”. E.g. you made some hard-coded assumptions about sizes of inputs that just happen to match the inputs in the unit test or you are referencing global variables in the notebook context from the local scope of your functions.
