What this page shows
Points come from student_points and every answer from practice_attempts. Both are written and graded by the server, so they are the same numbers students see. Click a student to see their runs, each question, the answer they chose and the right answer.
Schools compares sign-ups with the students who actually practise, and is where a school's agreement to reminder emails is recorded. Email reminder sends quiet students a short practice nudge; the server checks every student again (school agreed, still quiet, once a week, not stopped). Questions adds up the most recent runs to show which questions students get wrong most.
Filters, sorting and the open student are kept in the address bar, so you can share a view. Press / to search, ← → to move between students in the drawer.
