LockDown Browser® is a custom browser that locks down the testing environment within a learning management system.
Download the application from within your Canvas course. In your Canvas course, in the left-side column, click "Help" and select "Download Lockdown Browser" at the top of the options. For most courses, you will also need to use Respondus which requires a webcam.
If you have questions, talk with your instructor. Or, if you have problems installing the application, contact the OIT Help Desk.
