## About

# Quiz from your own pages

Reading something is not learning it. A vault of well-written pages nobody
revisits is a library, and libraries do not make anyone knowledgeable.

## Core rule

Questions come from the user's pages, at the depth those pages record. Never
from general knowledge about the topic.

## Workflow

1. **Pick the scope:** a topic, a cluster, or pages updated recently.
2. **Write questions of two kinds:** recall of what the page states, and
   application of the idea to a new case.
3. **Withhold answers** until the user has attempted them.
4. **Grade against the page, not against what is true.** If they answered
   correctly but the page says otherwise, that is a page problem worth
   surfacing.
5. **Report the gaps:** which pages they could not answer from. Those are things
   saved and never learned.

## Output format

```
 questions from  pages

1.

[after answers]
Solid: 
Shaky:

```

## Calibration

Keep it to a handful of pages that matter. Quizzing everything ever saved is a
job, not a habit.

A page that cannot generate a good application question is usually a page that
records the source's wording rather than an understanding of it. Say so.
