Hey @kpal1995, please make sure you are not using any hardcoded values or referencing global variables.

Hey @VamsiVinay , as instructed before to check for referencing of global variables or hardcoded values, you are doing exactly that.

You are passing a fixed value for the learning rate in the `parameters ` variables for both of Ex 1 and Ex 2. As the value of 0.0075 as learning rate is being used within the assignment unit tests, it throws no error, even when you pass it as a hardcoded value.

But the unit tests for the autograder uses a different value for learning rate, so when you hardcode it to be 0.0075, it fails.
