Verbal Classification
A reasoning task giving three words in one category; the answer is the option that belongs to the same category, while distractors fit only some stem words.
Verbal Analogy
An A : B :: C : ? item where the relationship between the first pair must be applied in the same direction to the third word to find the answer.
Sentence Completion
An item with one or more blanks in a sentence; the correct word must satisfy both the sentence's logic, including contrast or cause connectors, and its grammar.
Antonym
A word with the opposite meaning to a given word; antonym items require reading the target word's precise sense in context before choosing.
Synonym
A word with a meaning close to a given word; synonym items reward knowing fine shades of meaning rather than only a rough association.
Main Idea
The central point a passage conveys; passage questions ask for it, and the correct choice is supported by the whole text rather than one detail.
Inference
A conclusion drawn from stated evidence without being directly stated; valid inferences add no new claims beyond what the passage supports.
Prefix Clue
A word beginning such as un-, dis-, pre-, re-, or mis- that changes meaning in a predictable way and helps decode an unfamiliar word.
Suffix Clue
A word ending such as -less, -ful, -tion, or -able that signals meaning or part of speech and narrows the sense of an unknown word.
Context Clue
Surrounding words in a sentence that reveal a word's meaning; contrast connectors like although or but signal that the blank means the opposite.
Number Series
A sequence with a hidden rule; test constant differences, constant ratios, growing differences, and alternating or square patterns to find the next term.
Number Analogy
An A : B :: C : ? item with numbers; determine the operation linking A to B, then apply the same operation to C.
Number Puzzle
A grid or figure of numbers with one missing value; a fixed rule such as a constant row sum or outer-sum-equals-center determines the answer.
Arithmetic Sequence
A sequence in which the same number is added each step; the next term equals the last term plus that constant difference.
Geometric Sequence
A sequence in which each term is multiplied by the same factor; the next term equals the last term times that constant ratio.
Order of Operations
The rule that parentheses, then exponents, then multiplication and division left to right, then addition and subtraction left to right, govern a calculation.
Percent Change
The change divided by the original value, times 100; a percent increase followed by an equal percent decrease leaves a value below the original.
Mean
The sum of a set of values divided by how many values there are; if the mean of n numbers is m, their total is n times m.
Proportion
An equation stating two ratios are equal, a/b = c/d; it is solved by cross-multiplying to get a times d equals b times c.
Divisibility by 3
A number is divisible by 3 exactly when the sum of its digits is divisible by 3; the same digit-sum test works for divisibility by 9.
Divisibility by 4
A number is divisible by 4 exactly when its last two digits form a number that is a multiple of 4.
Figure Classification
A task giving three figures sharing a hidden feature, such as symmetry or number of sides; the answer is the option with that same feature.
Figure Analogy
An A : B :: C : ? item with shapes; describe how A changes into B, then apply that identical transformation to figure C.
Figure Matrix
A grid of figures with one cell missing; the missing figure must satisfy the rule running across its row and the rule running down its column.
Figure Analysis
A paper-folding task: a sheet is folded, punched, and unfolded; the answer shows the hole pattern found by reflecting punches across each fold line.
Fold Line
The crease created by folding paper; unfolding reflects each punched hole across that crease, so holes appear mirrored on the other side.
Rotation
A turn of a figure about a point, commonly 90 or 180 degrees; a 90-degree turn changes a vertical symmetry axis to a horizontal one.
Reflection
A mirror flip of a figure across a horizontal or vertical line; it reverses orientation while preserving size and shape.
Symmetry
A property in which a figure maps onto itself under a flip or turn; line symmetry means one half mirrors the other across an axis.
Enclosed Regions
The separate bounded areas inside a figure; counting them is a frequent rule distinguishing correct from incorrect classification answers.
Shading Inversion
A transformation swapping filled and unfilled areas of a figure; it commonly appears as the rule linking the first pair in a figure analogy.
Part Addition
A transformation that adds or removes a component of a figure, such as an inner shape or a line segment, between the first and second figure.
