Use case
Certification study fails in a predictable way: candidates read the official guide two or three times, feel fluent, and then cannot produce the answer under time pressure. Recall practice fixes the gap between recognising a fact and retrieving it. You add the study guide, standard, or manual to a space; the app pulls cards from it and keeps the exact passage each card came from, so when an answer looks wrong you can check the source in one click rather than trusting the generator. Scheduling uses FSRS-6, which returns each card shortly before you are predicted to forget it, so a fixed daily budget covers far more material than re-reading does.
A short adaptive check estimates what you already hold before you spend a single evening on material you know. It reports per-topic bands and a recommended first session rather than a single score.
Retakes compare against the previous run, so a topic that slipped is surfaced ahead of a topic that was never strong. That ordering matters more as the exam date approaches.
Most certification bodies publish a blueprint with weightings per domain. Organising a space by those domains means practice volume tracks the weighting instead of tracking which chapter you happened to read last.
The progress view shows mastery per topic, where mastered means three consecutive correct recalls, at least three weeks of retained interval, and at least one confident answer. One right answer does not count.
Every answer captures correctness and confidence. Answers you were sure about and got wrong are surfaced first, because those are the ones that survive into the exam room unexamined.
It will not tell you whether your study guide is current. If the standard has been revised, the cards inherit the old edition, and the source link is what lets you catch that.
