Ad 2. Yes, it's correct. But you have to keep in mind that when user starts some courses, and some of them have the same module(s) you could store only one mark for those modules. To prevent this you would need to create class like this:

class UtilisateurCourseModule(models.Model):
    user   = models.ForeignKey(Utilisateur)
    course = models.ForeignKey(Course)
    module = models.ForeignKey(Module)
    score = models.IntegerField()

Ad 1.

for c in user.course.all(): # why course not courses?
    print "Course {}".format(c.titre)
    for m in c.module_set.all().order_by('modulecourse__order')
        print "Module {}".format(m.titre)
        try:
            print 'score: ', UtilisateurModule.objects.get(user=user,module=m).score
        catch UtilisateurModule.DoesNotExits:
            print 'score: ---'
