SAT Math Guides.
In-depth lessons on the concepts the Digital SAT tests most. Each guide explains the idea from the ground up, works through real examples, and links to practice so you can apply it immediately.
The Digital SAT Math Guide
Everything about the math section in one place: the two-module adaptive format, the four content domains, the built-in Desmos calculator, grid-ins, timing, and how to prepare for each part.
10 min read → Test StrategySAT Math Study Plan
A realistic, week-by-week plan — 4-week and 8-week schedules, how to diagnose your weak spots, sequence the domains, and build the review habit that actually moves scores.
10 min read → Test StrategyHow to Get 700+ in SAT Math
Why Module 1 accuracy is everything, how to eliminate the careless errors quietly costing you points, and the short list of hard-question patterns you must master to break into the top tier.
10 min read → Test StrategySAT Math Tips and Tricks
Six tested strategies: plugging in answers, picking numbers, reading the question last, Desmos shortcuts, estimating to eliminate, and the two-pass pacing method.
9 min read → Test StrategyCommon SAT Math Mistakes
The twelve recurring errors that quietly cost students points — sign slips, misreading the question, grid-in mistakes, calculator over-reliance — with a concrete fix for each.
9 min read → CalculatorComplete Desmos Guide for SAT
Master the built-in graphing calculator: find roots and vertices, solve equations graphically, graph intersections, use sliders and tables, and know when hand algebra is faster.
10 min read → AlgebraHow to Solve SAT Linear Equations
The most-tested idea on the SAT. Isolating variables, the three line forms, systems of equations, and the no-solution / infinite-solution traps — all worked step by step.
8 min read → Advanced MathMastering SAT Quadratic Equations
Factoring, the quadratic formula, vertex form, and the discriminant. Learn to match the right method to each question and read a parabola on sight.
9 min read → Geometry & TrigSAT Geometry Formulas Explained
Which formulas the test provides, which you must memorize, special right triangles, circle arcs and sectors, and SOH-CAH-TOA — with worked examples.
8 min read → Test StrategyHow SAT Math Scoring Works
How the adaptive Digital SAT turns your answers into a 200–800 score, why Module 1 matters most, and what that means for how you should practice.
7 min read →Why written guides matter
Practice questions build speed, but they assume you already understand the underlying idea. These guides fill that gap. Read the lesson for a topic first, then head to the matching question bank to drill it, and finally take a full timed test to see it in context. If you're not sure where to start, the study plan sequences all of it for you across a 4- or 8-week schedule.
