Mathematical
Numbers, probability, algebra.
What we measure
Arithmetic fluency. Accurate, efficient calculation and unit handling.
Number sense & probability. Magnitude intuition, risk and likelihood judgments.
Algebraic reasoning. Translating words to equations, manipulating expressions, working with functions.
Quantitative modeling. Setting up solvable models, checking assumptions, estimation.
Why it matters
Mathematical strength supports sound decisions under uncertainty, clean budgeting, data work, coding logic, engineering thinking, and scientific reasoning.
How we test it
MCQ word problems and probability items check accuracy and reasoning. SJT items probe choice of method. SR captures study habits and comfort with numbers. OPEN prompts ask you to set up or justify a model. Items are adaptive; reports show score, tier, SE, and N.
Tips to improve
- Translate words → symbols; underline givens and units.
- Sanity-check with estimates and orders of magnitude.
- Practice probability trees and expected value.
- Work a few mixed problems daily; correct by writing the fixed method.
- Keep a mini "unit & formula" sheet and review spaced.
