E-learning tutorials consists of several independent course modules. During these sessions, a trainer supplies tutorial help via an electronic forum.
Trainees can join any module in any session.
If they are registered in a particular training session and cannot attend, they can transfer registration to another session. Note that the number of participants per session is fixed to a maximum of 6. They can send their questions starting from this date. When a self-training session is finished, the trainer provides the corrections of exercises proposed during the session.
