AssessmentMeasured, not scored. Sets your starting level.1 / 10
Where you start
What this lesson adds
Measure your current span so the Lab can pick the right starting point.
Step 1 of 2
This is a measurement, not a test
Four short sequences, each one digit longer than the last. You stop when you miss two in a row.
The result is not a score and it is not shared. It only decides which level the next lessons open at.
