Error when submiting

I dont know if i’m the only one who cant submit. In the Quiz website doesnt apear the submit button.
If someone can help me, i’ll be glad!
Thanks!

Hi,
It s probably normal since the mooc has ended one week ago. You can still do the exercices but quizzes give acces directly to the answers so I suppose the submit buttons are no more active.
The next session will start this fall
