Reporting a problem with a test

It helps to include:

• your device model, operating system version and browser;
• whether you were in fullscreen, and in portrait or landscape.

Please don’t send personal information you don’t need to share. We can’t provide repair advice for specific devices; for hardware faults, contact the manufacturer or retailer.
