Euclidiana: LSAT Logic Prep

Euclidiana is the focused way to drill LSAT logical reasoning — now with a Quant Gym of quantitative reasoning practice. Built by a Psychologist and test prep specialist for serious applicants who want clean, distraction-free practice that actually moves their score.

WHAT'S INSIDE • 326 original practice questions: LSAT-style logical reasoning across timed forms, plus the new Quant Gym • Sample the first question of any test — full explanation included — before you subscribe • Every form unlocks with a single subscription • Five reasoning categories: Necessary, Sufficient, Biconditional, Mixed, and Causal (correlation-vs-causation and post-hoc fallacies) • Every answer comes with a step-by-step explanation • Color-coded stimulus highlighting shows you exactly which words trigger each logical move • Built-in Venn and causal-chain diagrams visualize each relationship • Formal logic notation (P → Q, contrapositive, etc.) shown alongside plain English • Free Logic Reference: a built-in study section covering necessary/sufficient conditions, formal notation, conditional chaining, and common fallacies • Test Mode: a true timed exam simulation with no mid-question feedback and a full answer review at the end

NEW: QUANT GYM • 62 quantitative reasoning questions across four new forms: the Quant Sampler plus Quant Gym I–III, ramping Easy → Hard • Five areas: Arithmetic, Algebra, Geometry, Data Analysis, and Quantitative Comparison • The same step-by-step explanations as the logic forms — learn the method, not just the answer

WHY EUCLIDIANA Most prep apps drown you in features. Euclidiana strips it down to the one thing that raises your score: pattern recognition through deliberate, explained practice. No ads. No streaks. No social feed. Just questions, answers, and the reasoning behind them.
