32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Analogy bridge
- The specific relationship linking the first pair of words, such as part-to-whole or worker-to-tool. The same bridge must connect the third word to the answer.
- Odd one out
- A classification item where all but one word share a common property. The word lacking that property is the answer, so test each word against the rule.
- Antonym
- A word with the opposite meaning. In verbal items, pick the option that is a true opposite rather than a word that is merely unrelated or a weaker contrast.
- Synonym
- A word with nearly the same meaning as another. Synonym items ask you to choose the option closest in meaning to the target word.
- Sentence completion
- A sentence with a missing word. Read the full sentence, predict a fitting word from context clues, then select the option closest to your prediction.
- Word category
- A group of words sharing a class, such as birds, tools, or colors. Recognizing the shared class helps solve classification and analogy items quickly.
- Letter pattern
- A sequence of letters following a rule based on alphabet position, where A is 1 and Z is 26. Common rules are plus one, plus two, or reverse order.
- Part to whole
- An analogy relationship where one word names a piece of the other, such as wheel to car or petal to flower. The same piece-to-whole link must hold in the second pair.
- Function relationship
- An analogy link where one word names an object and the other names what it does, such as knife to cut. Apply the same use-based link to the second pair.
- Degree relationship
- An analogy link based on intensity, such as warm to hot. The second word is a stronger or weaker version of the first, and the same shift must apply to the answer.
- Number series
- A list of numbers following a rule. Find the difference or ratio between consecutive terms to reveal whether the rule is addition, subtraction, multiplication, or division.
- Alternating series
- A number series in which odd-positioned and even-positioned terms follow separate rules. Split the list into two sub-series before finding the next term.
- Growing difference
- A series where the gaps between terms themselves increase or decrease by a pattern, such as plus two, plus three, plus four. The next gap continues that pattern.
- Number analogy
- A pair of numbers linked by an operation, followed by a third number and a blank. Identify the operation on the first pair and apply it to the third number.
- Inverse operation
- The operation that undoes another, such as subtraction for addition or division for multiplication. Use it to isolate an unknown in a balanced equation.
- Place value
- The value a digit holds based on its position in a number. Each place is ten times the place to its right, so in 354 the 3 means 300.
- Equation balance
- The rule that both sides of an equals sign must stay equal. Any operation applied to one side must also be applied to the other side.
- Estimation check
- Rounding numbers to nearby tens or hundreds to judge the approximate answer. An option far outside the estimated range is almost certainly wrong.
- Pattern of shapes
- A repeating sequence of figures in which one attribute, such as side count, size, or shading, changes in a cycle. Track each attribute separately.
- Constant ratio
- A series rule where each term is multiplied by the same number, such as 3, 9, 27. Dividing consecutive terms reveals the ratio.
- Difference of terms
- The result of subtracting one term from the next in a series. A constant difference signals an addition or subtraction rule.
- Figure analogy
- A pair of figures linked by a visual change, followed by a third figure and a blank. Apply the same change, such as rotation or shading, to the third figure.
- Rotation
- Turning a figure around a point without flipping it. A rotated shape keeps its handedness, so a notch stays on the same relative side of the shape.
- Reflection
- A mirror image of a figure. A reflected shape reverses handedness, so a distinctive feature ends up on the opposite side from the original.
- Line of symmetry
- A line that divides a figure into two identical halves that match when folded. A figure may have zero, one, or many such lines.
- Paper folding
- A puzzle where paper is folded and punched, then unfolded. Each fold doubles the holes, and holes mirror across every fold line.
- Embedded figure
- A target shape hidden inside a larger drawing. The hidden shape keeps its exact size and orientation, so look for matching angles and side lengths.
- Figure classification
- A set of figures sharing a common property, such as number of sides or symmetry, with one figure that lacks it. That figure is the answer.
- Matrix puzzle
- A grid of figures in which each row and column follows a rule. The missing cell is found by applying the row and column rule together.
- Open versus closed
- A classification property: a closed figure has an unbroken outline enclosing space, while an open figure has a gap. This distinction often separates figures.
- Shading change
- A figure rule in which filled and unfilled regions swap or alternate across a series. Track shading separately from shape and position.
- Combining figures
- A rule where the third figure in a row is made by overlaying or joining the first two. Parts that appear in both may cancel out.
