The Intelligence & Reasoning section is often the defining factor in these objective exams. In the Sainik School (AISSEE) Class VI exam, for instance, Intelligence carries a massive 50 marks (25 questions of 2 marks each), and it holds similar weight in the Rashtriya Military Schools (RMS CET) paper. Because this subject isn’t taught in standard school curriculums, students are seeing it for the first time. The goal is to build their logical deduction skills from the ground up. Here is the complete, exhaustive Intelligence & Reasoning curriculum, broken down into Verbal and Non-Verbal categories, suitable for both Class VI and Class IX aspirants.
Part I: Verbal Reasoning (Logic & Language)
This section tests a student’s ability to understand, analyze, and solve problems expressed in words and numbers.
1. Series Completion
- Number Series: Identifying the mathematical pattern (addition, subtraction, prime numbers, squares, cubes) to find the next or missing number.
- Alphabet Series: Finding the missing letter or group of letters based on their positional values (A=1, B=2… Z=26).
2. Analogy (Relationships)
- Word Analogy: Finding the relationship between two words and applying it to another pair (e.g., Doctor : Hospital :: Teacher : School).
- Number/Alphabet Analogy: Extending mathematical or positional logic from one pair to another.
3. Classification (Odd One Out)
- Identifying the item that does not belong to a given group based on properties, categories, or mathematical logic (e.g., choosing “Iron” from a list of “Apple, Banana, Iron, Mango”).
4. Coding and Decoding
- Letter Coding: Shifting letters forward or backward in the alphabet.
- Number Coding: Assigning numerical values to words.
- Substitution Coding: Assigning new names to objects (e.g., “If red is called blue, what is the color of blood?”).
5. Direction Sense Test
- Understanding the four cardinal directions (North, South, East, West) and four inter-cardinal directions.
- Calculating the final direction or shortest distance from a starting point after a series of turns (requires basic Pythagoras theorem application for Class IX).
6. Blood Relations
- Decoding family trees. Solving statement-based problems (e.g., “Pointing to a photograph, a man said…”) and coded relations.
7. Ranking and Ordering
- Calculating total students in a row, or finding a student’s new position from the left/right after shifting.
- Comparing heights, weights, or ages (e.g., A is taller than B but shorter than C).
8. Mathematical Operations
- Substituting mathematical symbols (
) as instructed in the question and solving the equation using the BODMAS rule.
9. Logical Venn Diagrams
- Representing relationships between different groups using overlapping or distinct circles (e.g., representing “Animals, Dogs, and Cats”).
10. Clock and Calendar (Primarily Class IX)
- Finding the angle between the hands of a clock. Calculating the day of the week for a specific date or finding leap year patterns.
Part II: Non-Verbal Reasoning (Visual Logic)
This section relies entirely on images, shapes, and patterns. It tests spatial understanding and visual processing without relying on language.
1. Figure Series
- Observing a sequence of 3 or 4 problem figures and selecting the next logical figure from the answer choices based on rotation, addition, or deletion of elements.
2. Figure Analogy
- Establishing a relationship between the first two figures and applying the exact same transformation to the third figure to find the fourth.
3. Figure Classification (Odd Figure Out)
- Analyzing a group of 4 or 5 images and selecting the one that deviates from the common visual rule.
4. Mirror and Water Images
- Mirror Images: Lateral inversion (left becomes right).
- Water Images: Vertical inversion (top becomes bottom).
5. Paper Folding and Cutting
- Visualizing how a piece of paper will look when it is folded, a cut or punch is made, and then it is unfolded. This is heavily tested and requires strong spatial imagination.
6. Embedded (Hidden) Figures
- Finding a simple problem figure concealed within a larger, more complex answer figure.
7. Completion of Incomplete Pattern
Selecting a piece from the options that perfectly completes the missing quadrant of a geometric matrix or design.
