32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Verbal analogy
- A pair relationship problem of the form A is to B as C is to D. The link between the first two words must be matched in kind and direction by the second pair.
- Bridge sentence
- A short sentence linking two analogy words, such as 'a wheel is part of a car.' Comparing bridges for each option reveals which pair shares the same relationship.
- Odd one out
- A classification task in which all but one item share a category or attribute. The answer is the item that lacks the shared feature.
- Antonym
- A word meaning the opposite of another, usually matching it in part of speech. On verbal tests, a synonym is a distractor, not the correct answer.
- Degree relationship
- An analogy link where one word is a stronger or weaker form of another, as in warm to hot or drizzle to downpour. Intensity differs; category stays the same.
- Part to whole
- An analogy link where one item is a component of the other, such as petal to flower. Direction matters: whole to part is a different stem.
- Sentence completion
- A fill-in-the-blank item. Read the whole sentence, predict a word from context, then choose the option closest in meaning and grammar.
- Context clue
- Wording in a sentence that signals a blank's meaning, such as contrast words (but, although) or cause words (because, therefore).
- Function relationship
- An analogy link based on purpose, as in hammer to nail or scissors to cut. Both pairs must express the same use relationship.
- Category relationship
- An analogy link where one word is a type of the other, as in robin to bird. The second pair must show the same class-member link.
- Arithmetic sequence
- A number series in which each term changes by a constant amount, such as 4, 9, 14, 19. The next term adds that same difference.
- Geometric sequence
- A number series in which each term is multiplied by a constant factor, such as 3, 6, 12, 24. The next term uses the same multiplier.
- Alternating series
- A series made of two interleaved patterns, one in odd positions and one in even positions. Each subsequence follows its own rule.
- Second-level difference
- When consecutive differences are not constant, subtract again. A constant second difference means the series follows a quadratic rule.
- Number analogy
- A problem of the form a is to b as c is to d. Find the operation turning a into b, then apply the identical operation to c.
- Number puzzle
- A word problem giving a relationship such as a sum, product, or difference between unknowns. Translate it into an equation and solve for the requested value.
- Mean
- The arithmetic average, found by dividing the sum of all values by the count of values. Total equals mean multiplied by count.
- Median
- The middle value when numbers are ordered from least to greatest. With an even count, it is the mean of the two middle values.
- Perimeter
- The total distance around a shape. For a rectangle it equals twice the sum of length and width.
- Area of rectangle
- The space inside a rectangle, found by multiplying length by width. With fixed perimeter, a square maximizes this area.
- Quantitative comparison
- A task comparing two quantities. Adding or subtracting the same value from both sides preserves the comparison; multiplying by a negative reverses it.
- Estimation shortcut
- Rounding numbers to tens or hundreds before computing. This usually rules out all wrong choices quickly on multiple-choice quantitative items.
- Unit rate
- A ratio expressed per one unit, such as miles per hour or cost per item. Divide the total by the quantity to find it.
- Figure analogy
- A nonverbal item pairing two figures and asking for a third that relates to a fourth the same way. Identify the change, then apply it.
- Figure classification
- A nonverbal task where most figures share an attribute such as symmetry, side count, or shading. The answer is the figure that breaks the rule.
- Rotation
- Turning a figure about a point without flipping it. Shape and feature orientation are preserved, unlike a reflection.
- Reflection
- A mirror image of a figure across a line. It reverses left-right orientation, so a reflected figure cannot equal a rotated one.
- Line of symmetry
- A line that divides a figure into two halves that are mirror images. Counting these lines helps distinguish similar figures.
- Paper folding
- A sheet is folded, holes are punched, and the unfolded pattern is chosen. Unfold in reverse, mirroring holes across each fold line.
- Punch-hole doubling
- Each fold that a punched hole passes through doubles the number of holes on the unfolded sheet, giving up to two to the n holes after n folds.
- Cube net
- A flat pattern that folds into a cube. Faces opposite on the net can never appear adjacent on the assembled cube.
- Figure matrix
- A grid of figures where the rule across rows matches the rule down columns. A correct answer must satisfy both directions.
