Hey @W_Wurihan,
As you might have already figured out from the “Expected Output” and the errors that you have received, the shapes for multiple variables is wrong in your implementation. Did you make sure to run the for loop in the reverse order?

If your issue still persists, then please DM me your implementation for the L_model_backward function.

Cheers,
Elemento
