Heart of Algebra accounts for roughly a third of every SAT Math section. The College Board frames it as the ability to analyze, fluently solve, and create linear equations and inequalities — and to interpret what their solutions mean in context. If you walk into test day weak here, no amount of advanced math fluency will compensate, because Heart of Algebra questions appear in both the calculator and no-calculator modules and are usually front-loaded so they set the tempo for the entire section. Mastery looks like solving a two-step linear equation in under twenty seconds, recognizing parallel and perpendicular slopes by inspection, and translating an English sentence into an equation without rereading it. ScoreReady's Heart of Algebra drills are sequenced exactly the way the College Board sequences them: single-variable manipulation first, then inequalities, then two-variable systems, then linear function interpretation. Work them in order, untimed at first, then timed once you can produce clean worked solutions on paper. The worked solutions in every drill mirror the official College Board scoring rubric — every algebraic step is shown so you can compare line-by-line against your own scratch work and spot exactly where you slipped.

Study tips for Heart of Algebra
- When you see fractions in an equation, multiply both sides by the least common denominator before doing anything else. This single move eliminates the most common arithmetic slip on linear questions.
- Read the final question stem twice. The SAT often solves for x but then asks for 2x + 1 or for the value of an unrelated expression. Wrong-answer choices anticipate the half-finished solve.
- For systems of equations, scan first: if a coefficient is 1 or -1, substitution is faster; if coefficients line up to cancel cleanly, elimination is faster. Picking the wrong method costs 30 to 45 seconds.
- Inequality direction flips only when you multiply or divide both sides by a negative number. Circle the inequality symbol before you start so you do not lose it during the algebra.
- When a word problem describes "constant rate," "per hour," "fixed fee plus per unit," or "starting value," it is asking for a linear model in y = mx + b form. Identify slope and intercept before writing anything.
