Self-gradable answers
Answers a learner can honestly mark right or wrong in one glance.
What & why
After each card, the learner has to answer one question about themselves: did I know that? Deckberry’s whole schedule rides on that honest yes or no. If the answer on the back is a paragraph, they can’t give one — they knew some of it, blanked on the rest, and end up guessing at their own grade. Keep the answer short enough to judge in a single glance and the grading stays honest.
The rule
Make the back short enough to grade in one breath. If you can’t tell at a glance whether you got it right, it’s too long.
Bad → good

A paragraph — the learner can't cleanly say “did I know that?”
One crisp answer — an honest pass or fail every time.
When it applies
Any time the answer is open-ended or longer than a phrase. If the material genuinely has several parts worth knowing, that’s a sign to split it into separate cards — one crisp answer each — rather than cram them onto one back. See one card, one fact.
Extra context can still help memory — just move it off the graded answer. A short note below the answer teaches without muddying the pass/fail.
