The daily challenge is a short mixed set of questions drawn from across the subjects, refreshed each day.
Mixing subjects is deliberate. Practising one topic at a time feels more productive, but interleaving different types of question produces better long-term retention, even though it makes each session feel harder.
Frequently asked questions
- How often does the challenge change?
- Daily. Each day presents a fresh mixed set drawn from across the subjects.
- Why are the questions from mixed subjects?
- Because interleaving different question types produces better long-term retention than blocking one topic. It feels harder, which is part of why it works.
- How long does it take?
- A few minutes. It is designed to be short enough to do every day rather than something that needs setting time aside for.
