Every SAT question, one Rule.
Every SAT question type — codified into 140 Rules (98 R&W + 42 Math). Every Rule reduced to a CORD: Concept · Operation · Recognition · Drill. Every problem in the 2,064-problem bank maps to one Rule.
Concept
The single idea this Rule solves. One short paragraph.
Operation
The ordered procedure — Desmos keystrokes for Math, step-by-step text analysis for R&W.
Recognition
The wrong-choice pattern College Board loves to set, named so you spot it instantly.
Drill
30–60 wired problems per Rule, ordered easy → medium → hard.
