The server computes two averages for the work of each participant on each
13
sheet: a percentage of points obtained with respect to the number of points
3929 bpr 14
required, and the quality of points obtained on the exercises of the worksheet.
23 reyssat 15
Let x be the percentage and y the quality, both scaled proportionally
16
to values between 0 and 1. Here are the formulas for the computation of the
17
grades.

Remark : For level 0 and 1, if the quality of points is less than 1 for an
3571 bpr 42
exercise, the percentage of points obtained
7901 bpr 43
become 0% for this exercise when x is computed ; if the quality of points is betwwen 1 and 2,
3571 bpr 44
the percentage of points obtained for this exercise is divided by 2
45
when x is computed.

Pour cette feuille, votre enseignant a choisi le mode de calcul suivant
49
de la note.
50
Pour chacun des indicateurs suivants, on calcule la moyenne pour votre travail pour :
51
<ul>
52
<li>
53
!if $help_sw=0
54
  le quotient I des points cumulés par le nombre de points demandés 10*n
55
!endif
56
!if $help_sw=1
57
la moyenne I des n meilleures notes,
58
!endif
59
!if $help_sw=2
60
 le minimum I des n meilleures notes
61
!endif
62
</li>
63
<li>
64
la qualité Q des points obtenus sur les exercices.
65
</li>
66
</ul>
67
 
68
Si la note de qualité est inférieure à 1 pour un exercice,
69
I est mis à 0 pour cet exercice  ;
70
si la note de qualité est comprise entre 1 et 2,
71
I est divisé par 2 lors du calcul de la note de la feuille.
72
 
73
</p><p>
74
Ces moyennes sont ramenées entre 0 et 1 et
75
 la note de la feuille est calculée comme
76
\($scoremax * $(list[$help_level+1;]) \)
