ShattoPrep Unit Drills

Most unit mistakes aren't math mistakes. They're a flipped conversion factor, a forgotten gc, or 14.7 psia used where the local atmospheric pressure belonged. ShattoPrep Unit Drills is built around exactly those mistakes. STEP-BY-STEP UNIT CANCELLATION Every conversion shows each factor as a fraction with the cancelled unit struck through, so you learn the method, not just the answer. TRAP QUESTIONS • lbm vs. lbf: force, kinetic energy, and liquid-column pressure with gc • Gauge vs. absolute pressure, using the local atmosphere, not just sea level • Temperature vs. temperature difference: when the 32 and 273.15 apply, and when they don't TEMPERATURE SCALES °F, °C, K and °R, with the formula worked out for every conversion. FEEDBACK THAT NAMES YOUR MISTAKE Pick or type a wrong answer and the app tells you what went wrong, like "flipped the ft conversion factor" or "forgot to add atmospheric pressure." WAYS TO PRACTICE • Today's 10: the same ten questions all day, with a streak to keep • Topic drills: pressure, flow, length, mass and force, energy and power, density and viscosity, temperature, and each trap • Speed round: 20 questions against the clock, 5-second penalty per miss • Review weak spots: drills the topics you've been missing • Typed answers within 1% count as correct, and a miss shows how far off you were NO GUESSING TRICKS Questions are generated so that test-taking tricks, like picking the longest, the middle, or the odd-one-out answer, don't beat chance.
