Hallo Gordon,
Thank you for helping me so much !
I will take note of this, and the day I really need gradesfor this kind of activity, I'll have it right there
No, I didn't know about the redirection... I tried it, and it is done once everything is correct... "show next test" does not work in my case but anyways,
right now, I leave it as it is - instead of Moodle activity, just a link to the pages - because I actually never force students to anything (well, at least tecnically :D).
Thanks again, Gordon, I hope this will be helpful for some other people !
