1. When Creating a Test or Editing Test Options, you will see an option asking "Open Test in a New Window". For now, you should ALWAYS set this option to "No".
2. When Creating a Test or Editing Test Options, you will see an option called "Force Completion". This setting should also be set to "No". Force Completion means when you move away from the test for any reason, it will automatically submit the test and cause it to not allow re-entry. This means that for example if a student's Internet Connection flickers or the power fails or the browser crashes they will automatically be unable to re-enter the test and the test will be graded as is at that moment. A better option is to use the Set Timer option in the test settings and set Auto-Submit to "On". This means that when the student hits the amount of time you have allotted for that exam, the exam will automatically submit. If the browser crashes or the Internet flickers, they can re-access the test as long as they have not gone over the allotted time.
