About the Grade 8 Math diagnostic
Explore exponents, linear equations, functions, geometry transformations, and the Pythagorean theorem.
This diagnostic is a starting point rather than a practice exam: it samples the whole syllabus so you can see which units you already know and which ones need the work, before you spend study time guessing.

Common questions
- What does the Grade 8 Math diagnostic cover?
- It draws on all 10 units of Grade 8 Math: The Number System, Exponents and Scientific Notation, Expressions and Equations, Linear Equations and Functions, Transformations, Functions, Geometry, Data Analysis, Transformations, Statistics and Probability.
- Is the Grade 8 Math diagnostic free?
- Yes. The diagnostic and your results are free to use.
- What happens after I finish?
- Your results break the score down by unit, so you can see which ones cost you the most points, and you can start a study plan built from that result.
- Can I take it more than once?
- Yes. Each attempt draws from a different form, so a retake is new questions rather than the ones you just saw.
