Shortcuts & formulas

  • Name the relationship in the first pair in one sentence (worker-tool, part-whole, animal-young one, place-state), then apply the same sentence to the second pair.
  • Common analogy types: tool-user, tool-action, animal-home, animal-young, study-subject, creator-product, part-whole, cause-effect, synonym, antonym.
  • Number analogies: test squares, cubes, n(n+1), n^2 + 1, n^2 - 1 and simple ratios first.
  • Letter analogies: write the alphabet positions (A=1 ... Z=26). Look for a constant shift, reversed order or opposite letter (position sum 27).
  • Odd one out: find the property shared by three items (category, number type, gender, state of matter), then pick the item that lacks it.
  • For number groups check: primes, squares, cubes, multiples of a number, even/odd, digit sum.
  • If two options both seem to fit an odd-one-out question, look for the more specific common property.
