There seems to be a grading issue with the graded quiz. The question is to enter the rank of the provided 3x3 matrix. I entered the correct answer, but the feedback say that it’s wrong. I have a screen shot that I can post but I don’t want to post solutions.
I did pass the quiz so I can move on, however I don’t know where to submit the issue.
Thanks for not sharing the quiz questions and answers publicly. But there is probably no way we can figure out whether the problem is with the grader or with your answer without seeing the details. Please check your DMs for a message from me about how to proceed.
To close the loop on the public thread, we had a DM conversation to look at the actual results and it turns out not to be a problem with the grader.
