Math Tells
Structural patterns in how NSB Math questions are written — not the math itself, but tells and recognition shortcuts that save you time or let you guess from wording alone.
These hold across algebra, geometry, functions, calculus, and probability alike.
1. "Which of the following is NOT true / NOT a..."
Three choices state real, correct facts; one is false, and that false one is the answer. This shape recurs across every branch of math tested — the trick is remembering you're hunting for the wrong statement, not the right one.
2. Inside a "NOT true" question, look for a swapped paired-term
The false statement is very often built by taking a real fact and swapping in the wrong half of a commonly-confused pair — singular/non-singular, Type I/Type II error, increasing/decreasing, even/odd function — rather than inventing a random falsehood. Spotting the swap doesn't require solving anything, just recognizing two paired terms got crossed.
3. "Identify all of the following N that..." is a bonus format, not a fact
This exact phrasing is a fixed bonus template independent of subtopic. The instant you hear it, you know the answer is a numbered subset of the list just read — and "all of them" or "none of them" shows up as the real answer more often than an even split would suggest.
4. "What is the term/name for..." always wants one precise vocabulary word
Whenever a Short Answer stem asks for "the term," "the name," or "what we call" something, the expected answer is a single technical word or short fixed phrase — never a calculation or explanation. Commit to the vocabulary word the instant you recognize the concept.
5. "Convert ___ into ___" is a pure formula plug, not a reasoning problem
Any stem phrased as a unit or base conversion — feet to meters, Fahrenheit to Celsius, base-10 to hexadecimal — always resolves through one fixed conversion factor or procedure. Recognizing the "convert X to Y" shape tells you immediately that no clever insight is needed, just the right factor.
6. A named mathematician, theorem, or law locks in one fixed answer
When a stem invokes a specific named result, it's testing recognition of that name, not derivation — there's a single textbook-associated answer with no ambiguity to work through.
7. Word problems recur near-verbatim across different sets
A meaningful share of Math word problems are recycled with only the character's name changed. If a phrasing sounds familiar, trust your first instinct on the answer — it has likely appeared before with the same numbers.
8. Y is the single strongest letter lean of any NSB subject
Across all tracked Math MC questions, Y is correct about a third of the time — notably above the 25% baseline you'd expect from chance, and the strongest lean found anywhere in the NSB question set. If you are completely out of ideas on a Math MC question, Y is genuinely the best blind guess.
Exact tally across all 355 Math multiple-choice questions in the sample sets. Only reach for this if you are completely out of ideas and the clock is about to run out.
If you must guess completely blind: Y is the best single default of any NSB subject — a real, strong lean, though it should still never be used ahead of an actual attempt at the problem.
