Installing WebLock for Assess.ai including Computer Requirements

This article describes the process of installing WebLock (lockdown browser) ONLY for Assess.ai.  

WebLock is a special program that locks down the computer while you take a test, so that you can't surf for answers on the internet, or take screenshots of secure exam content.  This protects the integrity and validity of the exam.

You must install WebLock before you can take the exam, if your sponsor has required it.  You can uninstall it as soon as you are done.
