example score

4/16

Dimensional Analysis Knowledge (DAK)

Measures how confidently you use conversion factors, cancel units, and verify dimensional consistency across metric and compound-unit problems.

Foundations to strengthen

Developing command

Strong command

0 – 6: Foundations to strengthen | 7 – 12: Developing command | 13 – 16: Strong command

A score of 4 falls in the Foundations to strengthen range, suggesting you recognize some unit relationships but would benefit from more practice setting up conversions and tracking unit cancellation.
