Lockdown Browser will not install on my Chromebook
You cannot install Lockdown Browser on a Chromebook unfortunately. You can read more about our computer requirements here: https://intranet.brenau.edu/information-technology/student-computer-requirements/
I would recommend either going to the computer labs at most any campus as they all have Lockdown Browser pre-installed.
Another alternative is to go to remote.brenau.edu and use our remote lab environment. That should work fine on your Chromebook as well.
