The site works on computers, tablets and phones.
- Use a recent version of Chrome, Edge, Safari or Firefox.
- JavaScript and cookies must be on. Sign-in needs cookies, and the exams need JavaScript.
- A stable internet connection is needed. Practice exams and lessons load from the site as you go.
- Your browser remembers some settings for you on that device: exam answers in progress, your Listen settings and your silly effects choice. Clearing site data removes them.
- The Listen (read aloud) bar works in Chrome, Edge and Safari.
Payments happen on Stripe's own page, which the site sends you to and brings you back from.
