Difference same as expected value

Hello,

Can you explain to me what is wrong with my solution?
It looks like my difference is the same as expected but I still got an error.

No, we can’t see enough there to know what the problem is. There are a number of graded functions in that assignment. What is the actual grader output (“Show grader output”).

Fixed by @Almog_Tovim.

As stated in the notebook, there are intentional mistakes in backward_propagation_n that you can optionally fix. But you still get full marks if you don’t.

Good luck with the rest of the course :slight_smile:
