Dear Khun Jeab11 and other juniors
I think you have SUCCESSFULLY evaluate your peers' efforts but the problem was that you didn't see any change in the page. That's the way it works krub!
I remember that Ajarn once said that we can check if the assessment has been recognised by the D4L system by "REFRESHING THE PAGE". If the score you have given to such peer still shows at the same place you picked, it would mean that the assessment is SUCCESSFUL krub.
Maybe you can wait a little bit for Ajarn to explain this.
Enjoy the course!
