            &lt;b&gt;Creation of groups &lt;/b&gt;             &lt;p&gt;             The contest system is based on the creation of student groups. This helps to reduce the amount of information you need to provide before the contest (you declare groups, rather than every student). This also reduces the number of contest access codes (one per group).             &lt;/p&gt;&lt;p&gt;             To prepare for the taking place of the contest in your school:             &lt;/p&gt;&lt;p&gt;             &lt;b&gt;1. Make a list of "groups" your school needs. &lt;/b&gt;             &lt;/p&gt;&lt;p&gt;             A "group" consists in students having the same level and participating to the contest at the same time.             For example, if you wanted all the students from class 6e2 in the same hour, that's a group. If you wanted to have half of the class of 6e2 on one day (same hour) and another on a different day that would mean two groups. Students from different classes of 6th grade participating during the same hour, that's one group. If you want some students from 6th grade and some students from 4th grade to participate at the same time, that's two groups.             &lt;/p&gt;&lt;p&gt;             &lt;b&gt;2. In the GROUP tab, create your groups : declare the name, level, participation date, and the size of each group.&lt;/b&gt;             &lt;/p&gt;             &lt;p&gt;             &lt;i&gt;When creating groups, you don't need to provide the names of students. These informations will be provided by the students themselves when they start the contest.&lt;/i&gt;             &lt;/p&gt;             &lt;div style=&quot;border:solid black 1px;padding:5px&quot;&gt;             &lt;p&gt;             When creating each group, two codes will automatically be generated:             &lt;ul&gt;&lt;li&gt;&lt;p&gt;An &lt;b&gt;access code&lt;/b&gt; &lt;u&gt;for the students&lt;/u&gt; of the group, that they will use to access to the contest.&lt;br/&gt;             &lt;b&gt;Warning :&lt;/b&gt; the access code of a group will only work for 30mn starting from when the first student uses it to participate. It is there fore important to create at least as many groups as participation sessions.&lt;/p&gt;&lt;/li&gt;              &lt;li&gt;&lt;p&gt;A &lt;b&gt;secret code&lt;/b&gt; &lt;u&gt;destined only to the teacher&lt;/u&gt; who will supervise the group during the contest.&lt;br/&gt;             &lt;b&gt;Warning:&lt;/b&gt; It will be needed by the teacher in the rare case when a student is interrupted in the middle of the contest.&lt;/p&gt;&lt;/li&gt;&lt;/ul&gt;             &lt;/div&gt;             &lt;p&gt;             &lt;b&gt;3. Before the contest week, in the GROUP tab, print the information sheet destined to the teacher that will supervise each group.&lt;/b&gt;             &lt;/p&gt;&lt;p&gt;             This information sheet explains how the contest takes place and provide the group's codes.&lt;br//&gt;             &lt;/p&gt;             &lt;hr/&gt;             &lt;p&gt;             &lt;b&gt;Do you want to organize training sessions on past contests?&lt;/b&gt;             &lt;/p&gt;             &lt;p&gt;             Proceed in the same way, but don't forget that  &lt;u&gt;you will need different groups for the training and the contest.&lt;/u&gt;             &lt;/p&gt;
