All you need is a stable broadband internet connection, web browser, webcam, speakers and a microphone. (A live proctor watches you and listens to you during the exam.) The proctor will connect via GoToMeeting or Zoom. Linux Systems are not supported and can not be used to take the exam.
An on-screen keyboard will be available from the desktop to assist with entering characters such as curly brackets if you have an alternative keyboard layout, or please prepare a US Keyboard to take to the exam.
