THE TELL INDEX
Every CPA Exam Question Has a Tell.
Wrong answers give themselves away in 16 measurable ways. We ran every rule against real questions and kept the receipts. Click a card. Steal the point.
When two options are near-identical, the answer usually lives in that pair, and the difference between them is the exact concept being tested.

When two options say exactly opposite things, one of them is usually right. The writer built the question around that fork.

When three options are variations of one theme, the outlier is usually the answer. Strongest on NOT and EXCEPT questions, where three options are true statements and the stranger is your point.

The correct answer tends to share the most elements in common with the other options. Distractors are usually built by varying the correct answer one piece at a time, so the answer sits at the center of the family resemblance. This cue has a name in the research literature (Smith, 1982) and has been documented on professionally built standardized tests.

Wrong answers love absolutes: always, never, regardless, void, entirely, under no circumstances. Real rules of accounting and law are full of exceptions, so an option that allows none is usually describing a world that does not exist.

Absolutist logic hiding in polite vocabulary. No tell-word appears, but the claim allows no exceptions, like "information cannot be useful unless it is precise."

Right answers hedge: generally, usually, may, most, ordinarily. Carved-out exceptions are what true rules sound like. The mirror image of Bumper Stickers.

The option that echoes the stem's key vocabulary is right more often than chance. Correct answers have to engage the exact thing the stem asked about, and item-writing guidelines have warned test authors about this word-repetition cue for decades.

Not a tell. Math. Before computing anything, run three ten-second checks: direction, ballpark, ceiling. Which way must the answer point? Roughly how big must it be? What bound can it not cross? Options failing any check are dead, and they are dead by arithmetic, not psychology.

On many calc questions the numbers are decoration. Every option is really an inclusion decision or a concept decision wearing a dollar sign.

Where the number goes kills options faster than what the number is. Fair value or cost, OCI or net income, operating or investing. One classification sentence in the stem usually decides half the options.

An option that violates a hard definition is dead no matter what its number says. IRA distributions are never net investment income. Exempt is exempt.

On a pure-numbers ladder with nothing killable in the stem, the extremes are rarely right. Here is why the mechanism is real: distractors on calc questions are built from plausible mistakes, and plausible mistakes bracket the true answer. Forget a step and you land low. Double-count and you land high. The correct number ends up in the middle of its own error family.

The roundest number in the ladder is usually planted. Real answers come out of real arithmetic, and real arithmetic is rarely tidy.

When two surviving numeric answers differ by a small amount, the difference is the trap. The wrong one forgot exactly one step.

When one numeric option is exactly half of another, the pair is spotlighting a convention fork. Half-year conventions, 50% limitations, mid-period math.

What this page will not tell you
Tells do not pass the CPA exam. On our own measurements, the average question gives up one or two options to structure, and the rest is knowledge. Around one question in nine has four bare numbers and almost no structure to read at all. That is the part you drill for.
Every number above was computed by script against the full bank, and every one comes with its sample size so you can judge it yourself. When a tell tests weak, we say so. When a tell stops earning its spot, it comes off the page. If you find a place where a tell breaks, email us. Being wrong in public is the fastest way to get good at this.
20 questions, your section, full explanations. Free, no credit card.
Try the free sample examThese are metal detectors, not landmine maps. A tell tells you where to look. It never replaces knowing the material. Most of these turn one-in-four into a coin flip, and the concept flips the coin.
Every tell here has to pass one test: a reason the real exam itself would produce the pattern. Content logic, or the way exam distractors get built. Quirks of our own bank do not qualify, and we cut rules that fail that test.
