C3W3 quiz problem

1 and 2 weeks no problems. But in W3 since start I had problems. After lecture finishing the green sign does not appear (that I can move to the next lecture) No signs ‘completed’. I can’t open my quiz ML Interpretation. Please help me to solve this questions

Hi @Oleksandr_Ivashchuk,

Opening of your quizzes or labs is never dependent on “completion” of the lecture videos, that is, you don’t need to have green signs in order to open any lab or quiz.

Graded items require subscription to open.

Please try the following:

  1. First thing to do would be to log out of coursera and log back in, then try to open the quiz.
  2. Check if you have valid subscription to the course. It is possible that it recently expired.
  3. Share a screenshot with me of what you see when you try to open the quiz.


Dear Mubsi,
I have done 1,2 points due to recommendations. All ok.
I am sending 2 screenshots.

Hi @Oleksandr_Ivashchuk,

Thanks for this.

The screenshots tell that you have access and are able to open the quiz, which is good. But the issue actually is that the quiz does not load.

You can try:

  • Different browser
  • Different internet
  • Delete cache before opening
  • Try incognito mode

One thing I’d like to mention here is that since these quizzes are “practice” quizzes, they don’t necessarily need to be completed in order for the certificate or completion of the course. In order to compete the course, you just need to get the passing grade or higher in the programming assignments. All the other labs are quizzes are for your practise.
