Your students can take the quiz in Flexible format (on paper) or Online format (directly online, with audio questions). The Online format allows to test students' audio comprehension.
To set up an Online format, students need to have access to the contest's website and be able to play the audios. However, this format can be organized over several sessions throughout the contest period.
You can choose to have some of your students take the contest in the Flexible format, and others in the Online format.
