Mastering IQ & Aptitude Questions: Quick Prep Guide

IQ and analytical reasoning tests evaluate your pattern recognition, mathematical logic, and critical thinking skills. Review these core concepts and solving techniques before taking your practice test.

  1. Word & Concept Analogies

    Analogy questions test your ability to identify relationships between pairs of words or ideas and apply that same logic to another pair.

Common Relationship Types:

  • Function/Purpose: Pen : Writing :: Fork : Eating

  • Synonyms/Antonyms: Genuine : Authentic :: Transient : Temporary

  • Part to Whole: Page : Book :: Nucleus : Atom

  • Degree/Intensity: Warm : Hot :: Cool : Freezing

Pro Tip: Build a simple sentence using the first pair. For example: “A pen is used for writing.” Then apply the exact same sentence template to the second pair to find the correct answer.

  1. Number Series & Numerical Reasoning

    Number series require you to identify the underlying mathematical rule governing a sequence of numbers.

Key Patterns to Look For:

  • Arithmetic Progression: Constant addition or subtraction (e.g., 2, 5, 8, 11 -> +3 each step).

  • Geometric Progression: Constant multiplication or division (e.g., 3, 9, 27, 81 -> x3 each step).

  • Square & Cube Series: Sequences based on powers (e.g., 1, 4, 9, 16, 25… or 1^2, 2^2, 3^2…).

  • Fibonacci Series: Each term is the sum of the preceding two (e.g., 1, 1, 2, 3, 5, 8, 13…).

  • Alternating Sequences: Two distinct patterns interwoven into a single line.

Pro Tip: First calculate the differences between adjacent numbers. If the first difference isn’t constant, find the difference of the differences (second-level difference).

  1. Alphabet & Coding-Decoding Series

    Alphabet series test letter positioning, skipping intervals, or reverse alphabetical order.

Essential Solving Tricks:

  • Memorize Position Numbers: Assign each letter its numerical position (A = 1, B = 2, … Z = 26).

  • Use Benchmark Rules: Keep helpful memory aids like EJOTY (5, 10, 15, 20, 25) in mind to locate letters quickly.

  • Look for Skipping Patterns: Identify how many letters are skipped between terms (e.g., A, C, E, G skips 1 letter each step).

  • Reverse Coding: Pairs like A-Z, B-Y, C-X sum up to 27 in position numbers.

Pro Tip: Write down the numbers 1–26 above A–Z on rough paper before starting timed tests for rapid referencing.

  1. Shape & Spatial Reasoning

    Non-verbal questions evaluate your ability to analyze visual patterns, spatial transformations, and geometric rotations.

Key Elements to Track:

  • Rotation: Check if shapes rotate clockwise or counter-clockwise (e.g., 45°, 90°, or 180° turns).

  • Movement & Position: Track individual dots, lines, or shading moving across corners or grid positions.

  • Addition/Subtraction of Elements: Count sides, lines, or internal shapes increasing or decreasing systematically.

  • Reflection & Mirror Images: Identify horizontal or vertical axis flips.

Pro Tip: Focus on one specific detail inside the shape (like a small arrow or shaded corner) and follow its movement across figures before looking at the shape as a whole.
