Quick fire
Short multiple-choice rounds, how topic strength is worked out, why it fades, and the review queue.

What quick fire is
Rounds of 5, 10 or 20 short multiple-choice questions on a subject's ideas, each answered in a few seconds. They check that the basics are there. They aren't exam questions: those are in the question bank.
Starting a round
Open a subject. The Map shows its topics and subtopics with your strength in each. Start a round for the whole subject or for one topic from the map. Custom round sets the size, the mode, an optional timer and whether you get a second try after a wrong answer.
Answer with a tap, or with 1 to 5. Enter shows the answer and moves on; Esc leaves the round. Each answer is saved as you go, so a round left halfway still counts.
Try again
With Try again on (the default), a wrong answer doesn't show the right one. The choice you picked is marked wrong, with a hint, and you can pick again. Only your first pick counts.
How strength works
Each topic has a strength from 0 to 100%, shown as Weak, Building, Solid or Strong.
- A right answer adds to it. A right answer after a gap of some days adds much more than one repeated on the same day.
- Without practice, strength fades, the way memory does. The map tells you when a topic would drop noticeably in the next two weeks.
- One lucky answer can't make a topic Strong. A subtopic answered right in one sitting reaches Building; it takes spaced reviews over a few weeks to reach Strong.
There are no streaks or points. Strength only describes what you remember.
The review queue
Questions you missed last time, and ones you got right but are likely to be forgetting, go into a review queue. Review at the top of a subject's map plays a round from it. The review page has the queue across all your subjects.
A question leaves the queue when you answer it right.
Progress and history
Progress shows your strength over time, a forecast of the next 14 days without practice, the days you practiced and how many questions you've locked in. History lists your past rounds; open one to see every question, your answer and the explanation, or to retry the ones you missed.
A question looks wrong
