What you can study today

Core SAT Math topic areas

The SAT Math path focuses on durable problem-solving skills: reading the question carefully, choosing the right method, showing clean work, and checking the result.

Algebra and advanced math

  • Linear equations, systems, inequalities, and word problems
  • Quadratics, exponentials, functions, and equivalent expressions
  • Polynomial and rational expressions used in common SAT-style tasks
  • Graph interpretation, intercepts, slope, and rates of change

Data, geometry, and trig

  • Ratios, percentages, units, probability, and statistics
  • Tables, charts, scatterplots, and data-based reasoning
  • Lines, angles, triangles, circles, area, and volume
  • Right-triangle trigonometry and coordinate geometry review

Prep workflow

Practice, feedback and review for SAT Math

Diagnose

Begin with mixed questions so the system can separate topic gaps from pacing, reading, and arithmetic mistakes.

Practice

Work focused sets on the ideas that matter most, then return to mixed review so skills transfer across question types.

Correct

Use feedback loops to revise missed steps, explain the method, and rebuild the same skill from a new problem.
