I'm saying we are seeing this just-in-time feature/behavior in our instance right now. For example, during our finals we had an instructor re-open an attempt at the point that was past the time limit and past the "available until" date/time. However, the student was able to resume her attempt 3+ hours after beginning it when she originally was only given 2.5 hours AND we were past the original "available until" date/time. I have documented the examples I have encountered, and I am working with our CSM team.
Additionally, I believe the guides are reading differently. I've read them so many times, and I swear they used to reference certain changes only applying to a student's initial attempt if they haven't started the exam, otherwise the changes would be applied to future attempts. But, reading through them recently I'm only seeing a phrase like this one time. At this point, I may just be going crazy trying to keep up New Quizzes and I may be completely wrong. Haha!
Don't get me wrong, these are welcomed changes. However, like I stated previously, finding out about them in the middle of finals was a bit of a struggle.
