Common Formulas Cheat Sheet for SAT Math
Based on Lumist student data, while the SAT provides a geometry reference sheet, Geometry & Trigonometry still holds the highest overall error rate at 27%. Having a mental cheat sheet for advanced math and algebra formulas—and knowing when to just use Desmos—is the fastest way to improve your score.
Module 1 vs Module 2 Strategy
Based on Lumist student attempts, a significant portion of Cross-Cutting Strategy errors involve poor pacing across the adaptive modules. For example, our data shows that Geometry & Trigonometry questions have a 27% error rate (the highest), often appearing as time-sinks in the harder Module 2. Mastering Module 1 ensures you reach this higher-difficulty tier, which is mathematically required for a top score.
No-Calculator Strategies for SAT Math
Based on over 10,000 Lumist student attempts, 20% of geometry errors involve not recognizing special right triangles because students default to their calculators. Mastering no-calculator strategies helps you spot mathematical shortcuts, bypass tedious data entry, and finish the math modules with time to spare.
Transition Words Complete List for the SAT
Based on Lumist student attempts, 38% of errors on transition questions involve choosing a word that "sounds good" but doesn't match the logical relationship. Our data shows the most commonly confused pair is "however" vs "therefore," proving that you must rigorously test the logic rather than relying on your ear.
