I have a quiz where students are given 30 minutes to complete it. I ask students at the 28 minute mark if they need extra time. I have it set to give them 5 minutes from the current time. I have had it happen twice now where I gave students extra time and my moderate quiz says it gave them the extra time, but the students reported that the quiz ended after the original 2 minutes. Other students received the extended time and only those 2 students did not get the added time. The first time I would consider it a mistake by the student but the second time is more than a student error. I am wondering if anyone else has seen this issue and if there is anything I can do to ensure this does not happen again.
