Needed to stay signed in
Use an up-to-date version of Chrome, Edge, Firefox or Safari. The site works on phones, tablets and computers, with zoom up to 200% and with a keyboard.
For the best experience:
- keep cookies switched on, or you are signed out (see What cookies do you use?)
- for the final assessment, a computer or a recent phone both work, but a steady connection matters: the clock keeps running
- if something looks broken, reload the page, then try another browser
- update your browser and your phone's software if they are very old
- private or incognito windows work, but you may be signed out when you close them
The accessibility statement explains how we make the site usable for everyone.
