[Building Sakai] [Deploying Sakai] [Testing Sakai] Test & Quizzes Tool Errors and Bugs.

[Karen Tsao]

Hi Naira,

You have mentioned couple different scenarios. Let me summarize them here
and please correct me if I am wrong.

1. When the time is close to the end, the timer restarted. Can I know what
action the students have performed? What link/button they have clicked? Did
he log out and relog in?
2. Student got some system error log. Can I know what that log about?
3. Student got data discrepancy error. Did students get this during submit?
This error can happen when the backend server submit the assessment before
students submit it.

The only timed assessment issue we fixed after 2.7 is
https://jira.sakaiproject.org/browse/SAM-1184. Please take a look and see if
that looks like one of your scenario.

Are the 166 students taking the exam at the same time? We(Stanford) haven't
had timed exam with 166 concurrent students. It'll be good if other schools
can share their experience.

Thanks,
Karen
