Three real questions from the app, written for your year. No account, no email, nothing to install — and if you get one wrong, it tells you which mistake you made.
These three are hand-written, the same for everyone in your year, and deliberately easy — they exist so a first go cannot fail. The app itself reads a photo of tonight’s actual homework, works out which skills it is testing, and builds practice on those. Each skill carries a score that goes down when it is left alone, because that is what forgetting does.
