How it schedules your study
Each question carries its own memory model — how long you retain it and how
hard it is for you. The FSRS scheduler brings it back on the day you
are about to forget it, which is when a review buys the most retention per
minute. Miss something and it returns in a minute, then ten, then days out as
it sticks. Answer it cold three times and you will not see it again for weeks.
Sessions interleave across the exam areas instead of blocking one topic at a
time. Blocked practice feels easier and transfers worse — the exam does not
arrive one subject at a time either.
Set your exam date in Settings. The scheduler works
backwards from it, and without a date it cannot pace you toward anything.
