📝 Assessments

Mechanical Aptitude Test mechanical

Tests understanding of mechanical physics concepts including spatial reasoning, forces, levers, gears, fluid dynamics, and electrical circuits. Used primarily for technical and field operations roles.

Measures: Mechanical intuition, physics understanding, spatial reasoning, technical problem-solving

  • Review fundamental physics: forces, levers, pulleys, gears, pressure
  • Practise spatial reasoning and 3D visualisation
  • Work through mechanical problems systematically
  • Use process of elimination for uncertain answers
SHL Numerical Reasoning cognitive

SHL-administered data interpretation test using tables, charts, and graphs. Tests ability to analyse numerical data and draw accurate conclusions under time pressure.

Measures: Data analysis, arithmetic accuracy, percentage calculations, statistical reasoning

  • Practise reading SHL-format data tables and charts
  • Master percentage change and ratio calculations
  • Use estimation to verify answers
  • Pace yourself - don't spend too long on one question
SHL Verbal Reasoning cognitive

SHL-administered reading comprehension test. Passages followed by statements to evaluate as True, False, or Cannot Say based solely on passage content.

Measures: Reading comprehension, logical inference, distinguishing facts from assumptions

  • Answer based only on passage content, not general knowledge
  • Pay attention to qualifiers: some, all, never, always
