I would need the student to launch the ROPOT and take the test again

Sometimes it may happen that a student's connection breaks down while answering (e.g. when answering from home). You may also want to change the assignment and ask students to retake the test. In this case, you must first cancel the students' answers via

The Information system Teacher [course selection] (ROPOTs and Quizzes) Work with ROPOT remove answers (under the relevant ROPOT) or Remove answers (among the links at the bottom of the page)

You can cancel all responses from all persons or only the responses of an individual. You can cancel responses especially if you have set "no" or "Yes, they should, but it is always the same form (same questions) that should be offered to them." in the section dedicated to repetitive work with the ROPOT in the description of the ROPOT form. If it is a practice ROPOT with the setting "Yes, they should and some other questions should be offered to them next time they work with the ROPOT application.", the student simply launches the ROPOT creating a new session and the problem is solved.

Cancelled answers are not definitively lost. You can restore them using

The Information system Teacher [course selection] (ROPOTs and Quizzes) Work with ROPOT restore (under the appropriate ROPOT) or Restore discarded answers (among the links at the bottom of the page)

Also remind students to use the "Save and continue" button. In the event of a power outage or disconnection, it is then possible to return to a partially completed test and complete it.
