For the time being, the admins will be resetting tests for users who are disconnected while taking them. Kindly look out for further information regarding any changes to this procedure in the near future. 

Save the test often, because if you lose internet connectivity during the test, it will not automatically save your answers. When you save the test, the timer will continue to run, so you should immediately relaunch the test after saving so you do not run out of time.
