Two full-length practice tests (Module 1 + Module 2, 20 questions each), built to the exact difficulty ceiling of the digital SAT — the questions strong students most often miscalculate or misread. Every answer is instantly explained. Every solution is math-verified. No color used in print mode to save ink.
20 hand-picked hardest-tier questions covering systems, quadratics, circles, rational functions, exponentials, trig identities, and statistics — the exact traps that cost top scorers points.
A fully re-written second set — same hardest-tier topics, entirely new numbers and setups, so students can't just memorize Set A's answers. Same rigorous triple-verification.
