This diagnostic covers the core skills of six units: Ratio & Scale, Multiplicative Change, Multiplying & Dividing Fractions, Working in the Cartesian Plane, Representing Data, and Tables & Probability. Questions are mixed and ordered from easier to harder.

• Select one answer per question. You'll see whether you were correct immediately, with a short explanation.
• Use the small Hint button under a question if you get stuck.
• You may submit early, or the test auto-submits when the timer ends.
• After submitting, only your incorrect answers are shown for review — skipped questions are not scored.
