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

Tue Sep 13 02:10:09 PDT 2011

Dear Naira,

You please check the action log into sakai log table and check when the test
was submited and what actions students took in series. Sort it by time. You
ill be able to trace many things in this way. In other you can also check in
Apache Log the actions of the students. For that you might need to load into
excel and/or need to do some programming to trance or analyze the Apache
log.
