This mock module contains 20 hand-picked, high-difficulty questions drawn from the exact categories where Korean students most often lose points: extraneous roots, "infinite solutions" / "no solution" system conditions, complete-the-square circle equations, compound interest, remainder theorem, Vieta's formulas, and more. Every question is calculation-heavy โ exactly the kind that separates an 700 scorer from an 800 scorer.
