The daily challenge includes four tests, presented in random order. A new set of four tests is available each day.

These combinations of four tests were carefully chosen based on computer simulations demonstrating that they could accurately measure your C-Score, reasoning, short-term memory, and verbal ability in about ten minutes.

New challenges will be introduced over time to include other tests and target specific domains or lifestyle interventions.

We welcome your feedback and suggestions for challenges that you think would fit your lifestyle.
