Email and a password. Your school and subjects come next, inside the app.
No — any email works. A school email is not required, and nothing here asks your school to approve or pay for anything.
You land in the app. Your curriculum and subjects (up to 10, fixed once chosen) get set the first time you need them — there is no separate setup screen blocking you first.
Yes — a completely separate interface. Teachers get unlimited builds and unlimited digital sharing; students get on-screen practice. Neither can do the other's thing from their own account.
Building and sharing are free. Only printable PDF downloads are limited: 3 free for life, more when a colleague you invite signs up, or 30 a month for $30 a year.
Sign up separately for those — a teacher account is a distinct interface, not a role you toggle inside one account.
A teacher account covers one curriculum at a time (Cambridge IGCSE, for example) and up to 10 subjects inside it. That cap is fixed — not raised by referral or payment — so pick the curriculum you set the most tests for first.
