First, check the stage
These steps are for preparation before a timed attempt. If the exam is already running, use the exam-interruption guide and the support channel assigned to your programme before changing the setup.
Repeat the connection check
Confirm that your connection works and is stable. The published baseline is at least 1 Mbps upload; the actual equipment check must also pass.
Click the connection error or Check control, where available, to repeat verification.
Pause unrelated downloads and streaming, and close unnecessary high-bandwidth apps.
If permitted, try a more reliable connection, such as wired internet or a personal hotspot, then repeat the check.
Compatibility check keeps loading
Use a current browser allowed for the assignment. Close unrelated meeting or screen-sharing applications that may already be capturing the screen. Recheck required camera, microphone and screen permissions.
A VPN, extension or managed network can affect connectivity. Ask your IT administrator or support to diagnose restrictions on a managed device; do not disable organisation security controls yourself.
Still unable to start?
Send support the exact failing check, error, operating system, browser version and how long the check has been loading. If no suitable device or connection is available, ask the organiser about an approved alternative testing arrangement.
