## What is 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.
