How the Scales are Structured

example score

8/NaN

Radicals Knowledge (RK)

Measures how well you understand and apply core algebra skills involving radicals and rational exponents across common problem types.

Foundations to review

Developing command

Strong command

0 – NaN: Foundations to review | 7 – NaN: Developing command | 13 – NaN: Strong command

A score of 8 falls in the Developing command range, suggesting you can solve many standard radical problems while still benefiting from practice with multi-step simplification, equations, or rationalizing denominators.
