If you are getting blocked from taking an HonorLock exam due to camera or mic settings, you can check these settings in Chrome:
In Chrome, click on the 3 dots at the right
Then choose "settings"
Then choose "privacy and security" on the left
Then choose "site settings"
You'll want to look at the settings for both camera and mic. We'll choose camera first
In the "block" section, if honorlock is listed here, click on the trash can button to the right of it
Now go back to the "mic" setting and do the same thing.
Quit Chrome, reopen it, and try your test again
