When your instructor locks down a test or quiz, you cannot open other browser windows or use any other application while you are taking the test or quiz. For example, you cannot use a desktop calculator or open a different browser. Learning aids are not available when you are taking a locked-down test or quiz.
To take a locked-down test or quiz, you use the Pearson LockDown Browser. If you are working in a computer lab, the LockDown Browser is already installed. But if you are working on your own machine, you need to install the LockDown Browser.
