GAT (General Aptitude Test) Quantitative & Verbal Review

Comprehensive vocabulary flashcards covering key quantitative rules, arithmetic definitions, test structures, and verbal concepts from the GAT preparation materials.

GAT (General Aptitude Test)

A standardized examination available in Arabic and English versions that measures reading comprehension, logical relations, problem-solving behavior, inferential abilities, and induction abilities across Quantitative and Verbal sections.

GAT Test Structure

The breakdown of the test into two core domains: the Quantitative Part (including Algebra, Arithmetic, Pattern, Geometry, Comparison, and Data Interpretation) and the Verbal Part (including Analogy, Sentence Completion, Contextual Error, The Odd One Out, and Reading Comprehension).

CBT and PBT Attempt Limits

The policy allowing test-takers a total of $5$ attempts within $3$ years, divided specifically into $4$ Computer-Based Test (CBT) attempts and $1$ Paper-Based Test (PBT) attempt.

Number Sets Hierarchy

The nested mathematical classification of numbers consisting of Natural Numbers ($\mathbb{N}$: $1, 2, 3\dots$), Whole Numbers ($\mathbb{W}$: includes $0$), Integers ($\mathbb{Z}$), Rational Numbers ($\mathbb{Q}$), and Real Numbers ($\mathbb{R}$).

Prime Number

A natural number strictly greater than $1$ that has no positive divisors other than $1$ and itself, forming an infinite set (e.g., $2, 3, 5, 7, 11, 13, 17, 19, 23, 29\dots$).

Even Numbers

Integers that are evenly divisible by $2$, formally defined by the set notation $\{0, \pm 2, \pm 4, \pm 6, \dots\}$ or algebraic form $2k$, where $k \in \mathbb{Z}$.

Odd Numbers

Integers that are not divisible by $2$, represented by the set notation $\{\pm 1, \pm 3, \pm 5, \dots\}$ or algebraic form $2k \pm 1$, where $k \in \mathbb{Z}$.

Consecutive Numbers

A sequence of numbers that follow each other in order without gaps, such as consecutive integers ($11, 12, 13\dots$), consecutive even numbers ($8, 10, 12\dots$), or consecutive odd numbers ($17, 19, 21\dots$).

Order of Operations

The standard mathematical hierarchy for simplifying expressions: 1. Parentheses, 2. Exponents, 3. Multiplication & Division (from left to right), and 4. Addition & Subtraction (from left to right).

Greatest Common Factor (GCF)

The largest factor that two or more numbers share, determined by finding the prime factorization of each number and multiplying common prime factors with the lowest exponents.

Lowest Common Multiple (LCM)

The smallest positive integer that is evenly divisible by two or more numbers, determined by taking the highest power of each prime factor present, whether shared or unique.

LCM and GCF Relationship Formula

The mathematical identity establishing the relationship between the product, GCF, and LCM of two numbers: $\text{LCM}(a, b) = \frac{a \times b}{\text{GCF}(a, b)}$.

Divisibility Rule for 7

A rule stating that a number is divisible by $7$ if the number formed by dropping the ones digit minus twice the ones digit is divisible by $7$ (e.g., for $385$: $38 - (5 \times 2) = 28$, which is divisible by $7$).

Divisibility Rule for 11

A rule stating that a number is divisible by $11$ if the difference between the sum of its odd-positioned digits and the sum of its even-positioned digits equals $0$ or a number divisible by $11$.

Analogy Question

A verbal test item that presents a pair of words sharing a distinct logical relationship, requiring the examinee to select an answer choice reflecting the exact same relationship.

Bridge Sentence Strategy

A systematic strategy for solving verbal analogies by formulating a specific sentence linking the stem words together, and testing that exact framework against each answer choice.
