Week 2 assignment: Grader working wrongly

I passed all excersices inside the assignment, and the results were correct (matching to the expected values).
However, after sumbission of the assignment, it was graded 83/100.

This grade was the same aslo one week ago, as there were some issues with the excerise 5 (propagation). I uploaded the new version of assignment. Now exercise 5 has no issues, but the total grade is wrong.

How can it happen?!

Hi @Reza, are you still having an issue with this ?
