<p>
The server computes two averages for the work of each participant on each
sheet: a percentage of points obtained with respect to the number of points
required, and the quality of points obtained on the exercises of the worksheet.
Let x be the percentage and y the quality, both scaled proportionally
to values between 0 and 1. Here are the formulas for the computation of the
grades.
</p>

$table_header
$table_hdtr<th>Level</th><th>Formula</th><th>Explanation</th></tr>
$table_tr<td>0</td><td>$scoremax max(x,y)
 </td><td>Very lenient: maximum between percentage and quality.</td></tr>
$table_tr<td>1</td><td>$scoremax x
 </td><td>Quality is not taken into account. You get maximum of grade
 once all the required work is done.</td></tr>
$table_tr<td>2</td><td>$scoremax x y<sup>0.3</sup>
 </td><td>Quality has only slight effect over the grade.
$table_tr<td>3</td><td>$scoremax x y<sup>0.5</sup>
 </td><td>More effect of quality.</td></tr>
$table_tr<td>4</td><td>$scoremax x y
 </td><td>To have a grade of $scoremax, you must gather all required points
  (100%) without making any error (quality=10).</td></tr>
$table_tr<td>5</td><td>$scoremax x<sup>2</sup> y
 </td><td>Unfinished work is over-punished.</td></tr>
$table_tr<td>6</td><td>$scoremax x<sup>2</sup> y<sup>2</sup>
 </td><td>Any mistake is over-punished.</td></tr>
$table_end

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

Pour cette feuille, votre enseignant a choisi le mode de calcul suivant
de la note.
Pour chacun des indicateurs suivants, on calcule la moyenne pour votre travail pour :
<ul>
<li>
!if $help_sw=0
  le quotient I des points cumulés par le nombre de points demandés 10*n
!endif
!if $help_sw=1
la moyenne I des n meilleures notes,
!endif
!if $help_sw=2
 le minimum I des n meilleures notes
!endif
</li>
<li>
la qualité Q des points obtenus sur les exercices.
</li>
</ul>

Si la note de qualité est inférieure à 1 pour un exercice,
I est mis à 0 pour cet exercice  ;
si la note de qualité est comprise entre 1 et 2,
I est divisé par 2 lors du calcul de la note de la feuille.

</p><p>
Ces moyennes sont ramenées entre 0 et 1 et
 la note de la feuille est calculée comme
\($scoremax * $(list[$help_level+1;]) \)
