Interface in 8 languages: Spanish, English, Russian, Portuguese, Ukrainian, Hebrew, Arabic and Chinese (with right-to-left writing). Choose the language in the top menu or in “My account”.
A question with its image and answers fits on one screen; official comment and error reports are in collapsible tabs below.

“Found an error in this question?” button and a version history for every question.
More security: temporary lock after several failed attempts and a notice if someone resets your password or 2FA. The service is for people aged 18 or older.
Practice in the browser: choose subjects, exam years and the number of questions.
Spaced review: questions you get wrong come back the next day, then after 3, 7, 14 and 30 days.
Keyboard shortcuts (1–5, Enter, →), optional instant check and a link of its own for every question.
Dashboard with your progress: accuracy, bank covered, weeks and subjects.
