A speed drill only works if it's actually timed and actually adapts — a worksheet you can take as long as you like on doesn't train speed, it trains patience. Here's what makes a drill effective, and how to run one yourself.
Untimed practice lets you fall back on slow counting-up strategies instead of recall — and you won't notice, because there's no pressure telling you to. A visible countdown forces the faster pathway to develop.
Sixty seconds is long enough to answer a dozen-plus questions and short enough that you can do it daily without it feeling like a chore.
A single round tells you almost nothing — the number that matters is this week's average speed against last week's. That's the only way to know a drill is actually working rather than just being another thing you did.
Race's setup screen keeps the same difficulty and format every time specifically so that comparison stays honest.
