Many ISP's drop a user if they detect no activity for a certain amount of time. Unfortunately this can occur when you are taking a quiz, because the time spent without any interaction with the Moodle web server is considered idle time by the ISP. There are several possible work-arounds for this problem.
One work-around is to use a machine with an Ethernet connection such as the Library or Information Technology workstations in the Library and on the ground floor of the Library.
Another work-around is to generate network activity at various intervals by pressing the Save without submitting button.
If, however, a disconnect does occur, you may reconnect to Moodle and re-enter the quiz. You will receive a Continue the last attempt? prompt if you have resumed the quiz within the allowed time to complete the quiz.
A third work-around is for you to generate some Internet activity periodically, perhaps by manually initiating a pop-email process (check for new email).
