I've set up a lesson, and some students have made their attempts.
Unfortunately, we've discovered a minor problem in one lesson's page: The correct answer of a multichoice question page did not have the mark value properly filled in (a glitch in the Moodle 1.9->2.0 importing, probably), so the students never got a 100% score.
Now I've corrected the problem, but I don't find any way to regrade the attempts done so far. Does anyone know how to do it? Perhaps calling some PHP obscure function?
Thanks.
