Things to Remember

Browser Cache Settings:

It is always advisable to clear browser cache/cookies before starting any Mettl tests. For most browsers, pressing “CTRL+SHIFT+DELETE” and selecting Clear Cache (for Firefox and Chrome), does the job. In case any candidate faces any issue in loading the test or images, first shut down the system directly using the power button and then clear the cache again.

System Updates:

Mettl also recommends disabling security patches, updates of the anti-virus definitions and/or application updates (manually) during the test to avoid any interference while taking the test. You can disable automatic system updates for the duration of the test as they may lead to heavy downloads during the test and auto-system restart will hamper your test progress To disable System Auto-updates, follow the below steps:

  • For Windows, Go to ‘Start’ -> ‘Run’ -> Type Services.msc’ and then stop ‘Automatic Updates’ service.
  • In case you get a prompt that ‘Ports 1987 and 1988 have been blocked, please contact your network administrator to assist you with system permissions needed to run a web-cam proctored test.
