SAT prep Mathematics help — done properly

The Digital SAT Math section is adaptive — Module 2 difficulty depends on your Module 1 performance. The strategy is: nail Module 1 to unlock the harder Module 2, which is where the higher score comes from. A perfect Module 1 + average Module 2 still gets you ~720; the reverse caps at ~640.

Exam format you'll actually sit

Digital SAT Math: 2 modules of 22 questions each, 35 min each (70 min total). All questions calculator-allowed (Desmos built-in). Scored 200-800.

Highest-yield topics (the ones that show up year after year)

  • Linear equations + systems
  • Quadratic equations (vertex form, factoring, quadratic formula)
  • Exponents and exponential functions
  • Geometry: angles, circles, triangles, similarity
  • Statistics: mean, median, mode, standard deviation interpretation
  • Word problems with proportions and percentages
  • Function notation and composition

Drill these first. If you can't do every one of these cold, work through them with /explain or /problem-variants.

Common mistakes that quietly cost marks

  • Not using Desmos for graphing questions (saves minutes)
  • Misreading the question (always re-read the last sentence)
  • Spending >2 min on a question and not moving on
  • Geometry: not drawing the figure even when not provided
  • Word problems: not defining variables clearly

When you mark your past papers, tag each lost mark to one of these. The pattern reveals where to focus.

Where to get real past papers

  • Khan Academy SAT Practice (official partnership)
  • Bluebook app (College Board) — full-length digital practice tests
  • College Board Question of the Day
