Digit Recognition

Holding and tallying a stream of digits after it has gone.

Before you start

  • You have 3 minutes.
  • The digits are shown for 5 seconds, then withdrawn before the question.
  • Press 1–4 to choose an answer, or click it.

Next: two untimed worked examples, then the 3-minute run. The clock only starts when you begin the real test.
