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

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.
