Microsoft Forms quiz report show completion in seconds

[mikemdr]

We applied a quiz that was worth points to the students of our school and we noticed that several students took the test in less than 10 seconds even though they had to answer more than 10 questions. Even so, these students got most of the questions right. Is there any known bug in the Forms reports? What could explain such a short time to complete the quiz?

We are encountering the same issue here where responses were marked to be answered by students in seconds. Any responses yet from MS tech?
