The card builds the way the course builds: formation → writings and enforceability defenses → performance, conditions & breach → remedies → the UCC overlay and excuses. Explain the square in 30 seconds or leave it open. Solo, it's a gap finder. In your study group, it's caller mode — first correct explanation keeps the square, and the out-loud corrections are where the learning happens. The call sheet is the quiet hero: every rule in one plain-English line — expectation damages, perfect tender, foreseeability, the battle of the forms — so during exam week you stop playing and read it straight through as your attack outline. What's inside (4-page PDF, instant download):Page 1 — The card. A 5×5 grid: 24 doctrines + 1 free square. Your whole subject on one page.
