To retake a quiz on respondus, students should confirm with their instructor whether they are allowed to take multiple attempts of a quiz or not. If multiple attempts are allowed, then after the first attempt, close the browser and log out using your LIU student id and password. Go to Brightspace and click on ‘take quiz’ again then log into respondus lockdown browser to attempt the quiz.

When the LockDown Browser appears to “freeze”, it is commonly due to a dialog box from other applications running in the background and appearing underneath the secure LockDown Browser layer or there are corrupted web links, which are blocked. (LockDown Browser is a client web browser based on the same system components and settings that also make up IE on Windows and Safari on Macs.)
If the “Student Early Exit” feature is not available, no proctor is available to enter the “Proctor Exit Password” to close LockDown Browser, or the system is not responsive to the proctor exit password, the only option is a power down.
Because many systems put the computer into suspension when pressing the power button once, it will likely be necessary for you to force a power down by holding down the power button for 5 to 20 seconds or longer. Usually there is a small “chirp”, “click” or “beep” as the local drive heads are locked into transport position and the display discharges during the power down. Keep holding down the power button until the computer completely turns off. Ignore any messages that may appear on your screen during this process.
We recommend the following steps to restore any default settings after a power down. Please _do not_ attempt to remove LockDown Browser or perform any other restore methods before doing the following steps.
To restore the default settings on a Windows system:

1. Start the system from a power down (not suspension).
2. Start LockDown Browser
3. Immediately quit LockDown Browser
4. Log out of the Windows user account (do not use Windows Restart)
5. Log back into the Windows user account

To restore the default settings on a Macintosh system:

1. Start the system from a power down (not suspension).
2. Start LockDown Browser
3. Immediately quit LockDown Browser

If the student loses Internet connectivity in the middle of an exam, they can in most situations, use the “Student Early Exit” to close the browser with a valid reasons, resolve the underlying connection issue, restart the browser and continue the exam.
However, if the instructor enabled the option “Lock students into the browser until exam is completed ” when enabling the LockDown Browser requirement in the LockDown Browser Dashboard, the instructor or proctor will need to use an “exit password” under the “i” button or “About” button in the LockDown Browser toolbar to close the browser.
At the end of the message, we’ve included steps to restore with LockDown Browser if the system encounters a serious system error.

If you encounter any “spinning wheel” errors (and blanked out frame where your webcam image should be), it’s occurring because another program, background process, or privacy setting on your computer is preventing LockDown Browser from activating your camera.
