32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Analogy
- A pair relationship problem in the form A : B :: C : D, where the link between the first two items must be applied in the same direction to the third item.
- Synonym relationship
- An analogy link in which two words mean nearly the same thing, such as begin : start :: finish : end.
- Antonym relationship
- An analogy link in which two words have opposite meanings, such as hot : cold :: tall : short.
- Part to whole
- An analogy link where the first word names a component and the second names the object containing it, such as wheel : car.
- Category to member
- An analogy link where the first word names a class and the second names an example of it, such as fruit : apple.
- Degree relationship
- An analogy link based on intensity, where the second word is a stronger version of the first, such as warm : hot.
- Function relationship
- An analogy link where an object is paired with its purpose or use, such as scissors : cut :: pen : write.
- Classification item
- A verbal or nonverbal task giving several items that share a hidden attribute, with the answer being the option that lacks that attribute.
- Contrast signal words
- Words such as although, despite, except, and unlike that signal the blank in a sentence completion likely takes a meaning opposite to the stated idea.
- Sentence completion strategy
- Read the full sentence, predict a word for each blank, then eliminate options; with two blanks, both words must fit.
- Arithmetic series
- A number sequence in which each term changes by a constant amount, found by subtracting consecutive terms, as in 3, 7, 11, 15.
- Geometric series
- A number sequence in which each term is multiplied by a constant factor, found by dividing consecutive terms, as in 2, 6, 18, 54.
- Alternating series
- A number sequence that interleaves two separate rules, one governing odd positions and another governing even positions.
- Square number pattern
- A sequence of the form 1, 4, 9, 16, 25, where each term is a whole number multiplied by itself.
- Fibonacci pattern
- A sequence in which each term equals the sum of the two preceding terms, as in 1, 1, 2, 3, 5, 8.
- Number analogy
- A quantitative item in the form A : B :: C : ?, where the operation linking A to B is applied in the same order to C.
- Number puzzle rule
- A rule inferred from rows of three numbers, such as combining the first two to produce the third, then applied to the incomplete row.
- Order of operations
- The convention that multiplication and division are performed before addition and subtraction unless parentheses indicate otherwise.
- Divisibility by 3
- A whole number is divisible by 3 exactly when the sum of its digits is divisible by 3, as with 471 because 4+7+1=12.
- Divisibility by 9
- A whole number is divisible by 9 exactly when the sum of its digits is divisible by 9, as with 837 because 8+3+7=18.
- Percent benchmarks
- Common fraction-percent equivalents such as 1/2 = 50%, 1/4 = 25%, 1/5 = 20%, and 1/8 = 12.5%, used to compare quantities quickly.
- Second differences
- The differences between consecutive differences of a series; a constant second difference identifies a quadratic pattern such as 2, 5, 10, 17.
- Figure analogy
- A nonverbal item in the form A : B :: C : ?, where the transformation from A to B is applied to C.
- Rotation versus reflection
- Rotation turns a figure and preserves orientation, while reflection flips it across an axis and reverses orientation; a landmark feature distinguishes them.
- Matrix item
- A grid of figures governed by a rule across rows and down columns, with the task of selecting the figure that fills the missing cell.
- Paper folding
- A task in which a folded sheet is punched and then unfolded; the answer shows every hole produced by mirroring the punch across each fold line.
- Hole doubling rule
- Each unfold step mirrors existing holes across the fold line, so one punch through n folds can produce up to 2 to the n holes.
- Fold line exception
- A hole punched exactly on a fold line is not duplicated when the paper is unfolded, because the mirror image coincides with the hole.
- Line symmetry
- A figure has line symmetry when a straight fold through it maps the figure exactly onto itself, as with a square or isosceles triangle.
- Rotational symmetry
- A figure has rotational symmetry when a turn of less than 360 degrees maps it onto itself, as a square does at 90 degrees.
- Closed versus open figures
- A closed figure encloses a region with unbroken lines, while an open figure has endpoints; this attribute often separates classification options.
- Intersection count
- The number of points where lines cross; n straight lines in general position can create at most n times n minus 1, divided by 2, intersections.
