Units

1. UNIT 01

   Linear equations & inequalities in one variable

   Most SAT algebra questions come down to setting up a linear equation and solving it cleanly. Watch for questions that ask about the number of solutions instead of the solution itself.
2. UNIT 02

   Linear functions & systems

   Linear functions model constant rates. On the SAT you'll read slope and intercept in context and solve systems, often as word problems.
3. UNIT 03

   Equivalent expressions

   Equivalent-expression questions test algebra fluency: expanding, factoring and simplifying without errors.
4. UNIT 04

   Nonlinear functions & equations

   Advanced Math covers quadratics, exponentials and other nonlinear models. Know the forms and what each part means.
5. UNIT 05

   Ratios, rates, percentages & units

   These questions are about proportional reasoning: setting up ratios, working with percents and converting units.
6. UNIT 06

   Data, statistics & probability

   Data questions ask you to read tables and graphs, compare centers and spreads, and reason about samples and probability.
7. UNIT 07

   Lines, angles, triangles, area & volume

   Geometry questions use a handful of facts repeatedly. Many formulas are on the SAT reference sheet; knowing them cold saves time.
8. UNIT 08

   Right triangles, trigonometry & circles

   Right triangles and circles round out the SAT geometry domain. Expect SOH-CAH-TOA, special triangles and circle equations.
