Mettl test can either be:

1. Proctored- Using your live-video feed from your integrated webcam/USB webcam, you will be monitored by remote proctors or Mettl’s AI system.
   
2. Non- Proctored- No-live video feed is streamed. Hence no monitoring by remote proctors.
   

1. Network Speed

Mettl requires following minimum upload bandwidth (speed) to run online tests:

• For non-proctored test and AI proctored test - 512 kbps.
  
• For Media questions or Stored video or Authorization – 1 MBPS  

You can check your network speed using the following two websites:

1. http://bandwidthplace.com/
   
2. http://www.speedtest.net
   

If your network speed is above the advised speed, you should not a face a problem while attempting the test.

2. Supported Browsers

You can attempt Mettl tests on any of the following recommended browsers:

Browser	For (Proctored test)	For (Non-proctored test)
Chrome version	Google chrome latest three version	Google Chrome latest three version
Firefox version	Firefox latest three version	Firefox latest three version
Safari version	Safari latest three version	Safari latest three version
Microsoft Edge	Microsoft edge latest three version	Microsoft edge latest three version

1. Use the “allow once/always” pop-ups function from your browser settings to allow test window to open
   
2. Optionally, you may disable the pop-up blocker for the duration of the test. Here is how you can do it:
   
1. For Mozilla Firefox on Windows: Click the menu button    and select Settings -> Select the Privacy & Security panel -> Go down to the Permissions section -> Uncheck the box next to Block pop-up windows to disable the pop-up blocker altogether.
2. For Google Chrome: Go to ‘chrome: //settings/’ --> Click on 'Show advanced settings' (at the end of the page). Under 'Privacy and Security', click on Settings' > Privacy and security > site settings > Pop ups and Redirect’s > by clicking on > Sites can send pop-ups and use redirects, you’re allowing the site pop up’s.
3. Microsoft Edge:  Go to 'edge: //settings/content/popups' go to settings > Cookie’s and site permissions > Pop Ups and Redirect’s disable 'Block'.

After performing the above steps, please restart the browser.

 4. Things to remember

1. Browser Cache Settings: 
   

1.  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) helps you clear the cookies.
   

1. In case you still face any issue in loading the test, shutdown the system directly using power button and then clear the cache again.
   

1. System Updates:
   

1. Mettl also recommends to disable security patches, updates of the anti-virus definitions and/or application updates (manually) during the test in order 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.
   
2. To disable System Auto-updates, follow the below steps:
   
1. For Windows, Go to ‘Start’ -> ‘Run’ -> Type Services.msc’ and then stop ‘Automatic Updates’ service.
   
2. 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.
   

5. Firewall Settings

If you are attempting the test form your office or college premises, it may be possible that there are certain local network restrictions in the network firewall may be preventing the launch of Mettl tests. If you are facing any such issues, please contact your local network administrator and ask them to perform the following actions

Grant necessary firewall permissions to allow all requests from all subdomains of “mettl.com” in any of the following manner:

1. If possible allow all access from the network to *.mettl.com
   
2. If wildcards are not allowed in the firewall configuration rules, then please allow all access to the domain tabulated below:
   
1. *.mettl.com
   
2. tests.mettl.com
   
3. pr.mettl.com
   
4. media.mettl.com
   
5. node.mettl.com
   
6. api.mettl.com
   
7. static.mettl.com
   
8. chat.mettl.com
   
9. streaming.mettl.com*
   
3. Unblock the following domains
   
1. Domain      : (turnserver.mettl.com)
   
2. Ports TCP : 3478
   
3. Ports UDP : 3478 , Range 49152 – 65535
   

Opening these ports will make the service faster and efficient while giving you better quality images.

For webcam proctored tests, 

1. Firewall permissions to ports 1987 and 1988 for chat.mettl.com should be granted i.e.  chat.mettl.com:1987 and chat.mettl.com:1988 should be accessible & ensure that you have latest or updated version of Java installed.
   
2. Also, make sure that you uninstall any external webcam software (any third party/vendor software) from your system prior to starting the test.
