Week 2 quiz problem

the grader doesn’t allow me to retake the quiz. it stole from me two chances yesterday and today still is lucked

This is a known issue. Coursera is attempting to fix it.
There are no known work-arounds.

See this thread for updates:

thank you

I tried again few minutes ago, about 24 hours later, but still locked and due date is tomorrow.
any advice?

There’s no change in the status of this issue.

robots are overpowering humans?

facing the same issue and persists even after extending the deadline

same happen to me, it is a shame that coursera having an excellent program is not able to resolve this issue.
