Updated each time another 5 have played it to the end, so no one can be recognised.
Under the heading How it went, when at least 5 have played the quiz to the end: the numbers, e.g. how many played it and how many were right, change only when 5 more have finished, so the teacher can't see one pupil's answers by comparing before and after
Liczby zmieniają się dopiero wtedy, gdy kolejne 5 osób przejdzie quiz do końca, żeby nie dało się nikogo rozpoznać.
