What comes back today.
Every question you got wrong, guessed or bookmarked returns, but not on the same schedule. A question you guessed right is a question you do not know yet, and PRISM treats it that way.
The fact is not there yet, so it returns while it can still be caught.
0due todayYou got the mark but could not have defended it. Back sooner than you would like.
0due todayThree clean passes and it leaves the ledger for good.
0due todayNot a fixed ladder. One rhythm per outcome.
Most revision tools space a question on a fixed ladder (tomorrow, then four days, then ten, then twenty-five) whatever happened when you saw it. That treats a question you were certain of and one you got right by crossing off two options as the same thing. They are not. In a paper that is now two-thirds statement-type, the second one will cost you eventually. So PRISM asks for the outcome.
Back tomorrow. A wrong answer means the fact is not there at all, and the first repetition has to be close enough to catch it before it fades again.
The honest middle. You got the mark, but you could not have defended it. The setting most aspirants never admit to, and the one that decides borderline results.
Three clean passes and the question leaves the ledger. Revision you do not need is revision stolen from something else.
Changing your answer changes your ladder. Say you knew something you had been guessing, and it moves across; get something wrong that you had known, and it goes back to tomorrow. The ledger follows you, it does not grade you.
Missing days does not build a wall
Anything more than a week overdue moves into a backlog rather than piling onto today. The backlog drains a dozen a day, oldest first, alongside whatever is genuinely due. Come back after a fortnight away and you get a normal session, not two hundred cards and a reason to quit.
Where questions come from
- Anything you get wrong in the daily quiz or a test.
- Anything you grade as guessed or wrong in the Archive.
- Anything you bookmark or send over by hand.
Everything stays on this device, and is backed up to PRISM under your own private key if you have a free practice profile. The key is what unlocks it, never your email on its own.
