- Ecology: Basic concepts of ecosystems and environmental interactions.
Example: A question might ask, "What is the SI unit of power?" or "Which gas is commonly known as laughing gas?"
2. Mathematics: Sharpening Your Numerical Skills
This section evaluates a candidate's arithmetic and logical reasoning abilities related to numbers. The questions are generally at a 10th-grade level and focus on accuracy and speed.
Arithmetic:
- Number System: Properties of numbers, divisibility rules, LCM (Least Common Multiple), HCF (Highest Common Factor).
- Fractions and Decimals: Operations on fractions and decimals, simplification.
- Percentages: Calculating percentages, profit and loss, discounts.
- Ratio and Proportion: Solving problems involving ratios and proportions.
- Averages: Calculating the average of a set of numbers.
- Time and Work: Problems related to individual and collective work rates.
- Time, Speed, and Distance: Calculating time, speed, or distance in various scenarios, including trains and boats.
- Simple and Compound Interest: Calculating interest amounts and final sums.
Algebra:
- Basic Algebraic Identities: Solving equations using identities.
- Linear Equations: Solving simple linear equations.
Geometry:
- Triangles, Quadrilaterals, and Circles: Properties, area, and perimeter calculations.
- Basic Theorems: Understanding fundamental geometric theorems.
Trigonometry:
- Basic Trigonometric Ratios: Solving simple problems using sin, cos, and tan.
Example: A typical question could be, "If a train travels 300 km in 4 hours, what is its average speed?" or "Find the simple interest on $5000 at 8% per annum for 2 years."
3. General Intelligence and Reasoning: Testing Your Analytical Prowess
This section is designed to assess a candidate's ability to think logically, identify patterns, and solve problems. It’s less about rote memorization and more about cognitive skills.
Verbal Reasoning:
- Analogies: Identifying relationships between words or concepts.
- Series Completion: Completing numerical or alphabetical series based on identified patterns.
- Coding-Decoding: Deciphering coded messages or words.
- Blood Relations: Solving puzzles based on family relationships.
- Direction Sense: Determining positions and directions based on given statements.
- Syllogisms: Drawing logical conclusions from given statements.
Non-Verbal Reasoning:
- Pattern Recognition: Identifying missing figures or completing visual patterns.
- Spatial Visualization: mentally manipulating shapes and figures.
- Figure Formation and Analysis: Analyzing and interpreting geometric figures.
- Cube and Dice Problems: Problems involving the visualization of cubes and dice.
Analytical Reasoning:
- Seating Arrangements: Solving puzzles involving the arrangement of people in a line or around a table.
- Logical Deduction: Drawing conclusions from a set of premises.
Example: A question might be, "If 'CAT' is coded as '3120', how will 'DOG' be coded?" or "Find the next number in the series: 2, 5, 10, 17, 26, ____."
4. General Awareness and Current Affairs: Staying Informed
This section tests a candidate's awareness of current events and general knowledge about the world around them. It covers a broad range of topics.
Current Affairs:
