To take an online test, start LockDown Browser and navigate to the exam. (You won't be able to access the exam with a standard web browser.)

For additional details on using LockDown Browser, review this Student Quick Start Guide (PDF)

Finally, when taking an online exam, follow these guidelines:

  • Select a location where you won't be interrupted
  • Before starting the test, know how much time is available for it, and that you've allotted sufficient time to complete it
  • Turn off all mobile devices, phones, etc. and don't have them within reach
  • Clear your area of all external materials — books, papers, other computers, or devices
  • Remain at your desk or workstation for the duration of the test
  • LockDown Browser will prevent you from accessing other websites or applications; you will be unable to exit the test until all questions are completed and submitted
