Answer 1

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: ---'

Answer 2

SOLVED

1- This is how I've managed to do it :

    course = Utilisateur.objects.get(user=current_user).course.all() 

    course_sets = []
    for p in course:
        modules = Module.objects.filter(course__id=p.pk).order_by('modulecourse__order') 
        modules_sets = []
        for m in modules:                
            score = UtilisateurModule.objects.get(module=m,utilisateur=current_user)
            modules_sets.append((m, score))
        course_sets.append((p, modules_sets)) 

2- I added course = models.ManyToManyField('Course') to Utilisateur

and then added some manual verification that whenever A course is affected to a user the modules in that course are also affected to the same user in UtilisateurModule
