Other notes:
- Mobile devices are not supported to work with CertMaster. It may be possible for some tablets and phones to play our videos and display our fact sheets to a limited extent but quizzes and lab simulations are disabled on tablets and phones. There is no mobile app. Click here for more information.
- An external computer mouse is recommended. Touch screens are not supported.
- CertMaster lab simulations can be sensitive to screen size, so smaller screens may benefit from a reduced browser zoom setting.
- CertMaster is entirely online and lab simulations, quizzes, and videos are not available for download.
