Casper / Study guide
Free to read · No login requiredA short, original guide to the Casper test: one method (the DECIDE approach), many everyday examples, and many model answers, weak and strong. Free to read, no paywall.
Why this book
Casper rewards consistent, well-reasoned answers under time. This book teaches exactly that, with examples you can feel.
A single routine you run on every scenario: define the dilemma, examine perspectives, choose and justify, deal with consequences. No inventing structure under the clock.
Casper scores how you reason, not which option you pick. The book trains the reasoning raters reward, and the moves that separate strong answers from weak ones.
The fastest way to learn a strong answer is to see a weak one beside it, with the difference named. The book is full of original weak-versus-strong rewrites and fully worked scenarios.
Built to be read and drilled in two focused days, with everyday examples and timed-practice guidance for both the typed and video sections.
Contents
Five parts plus reference appendices. Start at the beginning or jump to the part you need; every chapter has its own contents, dark mode, and a reader view.
What Casper is, why it is learnable, and how to study it in a couple of days.
How the test works and how it is scored: the two sections, the per-scenario clock, the human raters, and the quartile you receive.
How raters read your answer, the DECIDE method you run on every scenario, and how to aim it at each Casper question type.
The moves that earn marks, the failures that cost them, and weak-versus-strong rewrites of the same prompts.
The nine competencies Casper assesses, what a strong answer shows for each, and the common miss.
Full worked scenarios with model answers, plus typed and video strategy, a two-day study plan, and test day.
Keep these beside you while you drill: the DECIDE templates and timing, and the nine-competency cheat sheet.
The book teaches the reasoning; our Casper practice platform gives you full-length, human-scored practice with the feedback the official test never provides.
