<h2 id="exotrymax">Maximal number of attempts</h2>

This parameter defines a maximal number <span class="tt">n</span>

of attempts to be used in the calculation of grades when score recording is open on the sheet.

<p>

If you do not want to set a maximum value, leave this field empty.

</p>

<p>

<strong>Attempt or try</strong>: working on a series of exercices counts

as an attempt whether or not an answer is supplied

and whether or not score recording is enabled.

</p>

If a postive number <span class="tt">n</span> is supplied

<ul><li>

one still may work on the exercise after this number is attained;

</li><li>

the attempt counter is incremented only when score recording is open on the sheet by the teacher.

</li><li>

the grade calculation uses only the scores for the <span class="tt">n</span>

first attempts with score recording activated. Therefore, the required point number for the exercice

cannot exceed <span class="tt">10 x n,</span> as this is the maximum number of points

</li></ul>

<h2 id="weightexo">Weight of an exercise in the sheet</h2>

The weight of an exercise in the sheet is used in the calculation of three work

estimators on a sheet

 - <span class="wims_code_variable">$(wims_name_thsheet[5]),

$(wims_name_thsheet[10]), $(wims_name_thsheet[13])</span>

and in the calculation of the score <span class="wims_code_variable">$(wims_name_thsheet[7])</span> de la feuille.

<ul><li> The value of the indicator <span class="wims_code_variable">$(wims_name_thsheet[5])</span>

is the weighted arithmetic mean of the scores from the exercises of the sheet,

of the exercise in the sheet by the required points number.

A similar rule is used to compute the value of

<span class="wims_code_variable">$(wims_name_thsheet[10])</span>

and <span class="wims_code_variable">$(wims_name_thsheet[13])</span>.

</li><li> The grade <span class="wims_code_variable">$(wims_name_thsheet[7])</span>

 on the sheet is a weighted mean of the quality note obtained for each exercise,

 the weight being the product of the the weight of the exercise in the sheet by the

 the running total estimator on the exercise.

</li></ul>

<p>

A value of 0 means you do not want the scores from this exercise to be used.

Example: This spreadsheet shows the results for a student on a sheet with 3 exercises:

$table_header

  <thead>

  $table_hdtr

    <th scope="col" data-sort-method="number">$(wims_name_thsheet[1])</th>

    <th scope="col">$(wims_name_thsheet[2])</th>

    <th scope="col" data-sort-method="number">$(wims_name_thsheet[3])</th>

    <th scope="col" data-sort-method="number">$(wims_name_thsheet[4])</th>

  !!qualite

    <th scope="col" data-sort-method="number">$(wims_name_thsheet[7])</th>

    <th scope="col" data-sort-method="number">$(wims_name_thsheet[5])</th>

  </tr>

  </thead>

  <tbody>

<tr><td> 1 </td><td>Exo 1</td><td>20</td><td>2</td><td>5.5</td><td>60%</td></tr>

<tr><td> 2 </td><td>Exo 2</td><td>10</td><td>3</td><td>6.5</td><td>25%</td></tr>

<tr><td> 3 </td><td>Exo 3</td><td>10</td><td>0</td><td>8.5</td><td>100%</td></tr>

  </tbody>

$table_end

<ul><li>

The score $(wims_name_thsheet[5]) on the sheet is

\(\frac{2\times 20 \times 60 + 3 \times 10 \times 80 + 0}{2\times 20 + 3 \times 10}\% = 68.57\%\)

</li><li>

The score $(wims_name_thsheet[7]) on the sheet is

\(\frac{2\times 60 \times 5.5 + 3 \times 80 \times 6.5 + 0}{2\times 60 + 3 \times 80} = 6.17\)

</li></ul>

If you check <span class="tt">$wims_name_yes</span>, the exercise description

will appear in the exercise header, not only in the list of the exercise in the sheet
